"The app is not working" describes a dozen different failures with different causes. Before you raise a ticket or conclude the vendor is at fault, work through these checks in order — cheapest and most likely first. In my experience the great majority of cases resolve before step four, and the ones that do not become much easier for support to fix because you arrive with real diagnostic detail.
Step 1: Is It You, or Is It Them?
Establish scope first, because it determines everything else. Check whether the same account works in a desktop browser, and whether a colleague on a different device and network has the same problem.
- Works on desktop, fails on mobile — a client-side or app-specific issue. Continue to step 2.
- Fails everywhere for you, works for colleagues — account, permission, or data-specific. Skip to step 5.
- Fails for everyone — likely a vendor outage. Check the vendor status page and their social account before spending time on your own setup.
This single test eliminates most wasted effort. Do it before anything else.
Step 2: The Boring Fixes That Usually Work
In order, because each is cheaper than the next:
- Force-close and reopen. Not minimise — actually terminate the app.
- Check for an app update. Server-side API changes routinely break older client versions, and this is one of the most common real causes.
- Check the OS version. Apps drop support for older Android and iOS releases, sometimes without a clear message.
- Restart the device. Clears stale network state and orphaned background processes.
- Confirm available storage. A device near full causes symptoms that look nothing like a storage problem: failed sync, blank screens, silent crashes. Anything under about 1 GB free is a genuine suspect.
- Clear the app cache (Android) or offload and reinstall (iOS). Try cache before data — clearing data will sign you out and may discard unsynced work.
Before clearing app data, make sure anything created offline has actually synced, or you will lose it.
Step 3: Network — The Most Misdiagnosed Cause
"I have internet, other apps work" does not rule out a network cause, because SaaS apps need specific hosts and ports rather than general connectivity.
Switch networks entirely. Move from office Wi-Fi to mobile data, or vice versa. If it works on one and not the other, you have found the problem and it is almost certainly network policy, not the app.
Common culprits, particularly on Indian office and hotel networks:
- Captive portals. Hotel and café networks that require a browser login intercept traffic and break API calls while appearing connected.
- Corporate firewalls or content filters blocking the API domain even though the marketing website loads.
- VPN interference. Try with the VPN off; also try with it on, since some networks only work through it.
- DNS problems. Test an alternative resolver. Some ISP DNS failures affect only certain domains.
- Battery saver and data saver modes. Aggressive Android power management restricts background sync, which typically presents as "it only updates when I open the app".
On Android, also check whether the app has been granted unrestricted battery usage. Manufacturer-specific power management is a very common cause of sync that works intermittently.
Step 4: Login Loops and Session Failures
Being returned to the login screen repeatedly, or signed out constantly, usually has one of four causes.
Device clock drift. Authentication tokens are time-sensitive. If the device clock is wrong by more than a few minutes, tokens are rejected as expired. Set date and time to automatic — this fixes a surprising share of login loops and is almost never the first thing people check.
Single sign-on misconfiguration. If you sign in via Google or Microsoft, test that account elsewhere. Expired SSO certificates or changed group membership present as an app problem.
Session limits. Some plans cap concurrent devices, silently signing out the oldest session. If you rotate between phone, tablet and laptop, this looks random until you know the rule.
Mobile device management policy. On managed work devices, MDM can block app data access, certificate pinning, or clipboard behaviour. Symptoms are strange and inconsistent. If the device is enrolled in company management, involve whoever administers it early rather than late.
Step 5: Account, Permission and Data Causes
If the failure follows your account rather than your device, look at:
- Subscription state. A failed payment often degrades access quietly instead of announcing itself. Verify billing status directly.
- Role and permission changes. Losing a permission can make a screen render blank rather than show a clear error.
- A specific problem record. If the app crashes only on one screen, one malformed record is often responsible. Note exactly which item triggers it — this is the single most useful thing you can tell support.
- Data volume. Mobile clients handle large datasets less gracefully than web clients. Apply a filter or date range and see whether the screen loads.
What to Send Support So They Can Actually Help
A ticket saying "app not working" gets a generic reply asking you to reinstall. Include instead:
- Exact app version, OS version, and device model
- What you did, what you expected, what happened, with the exact error text or a screenshot
- When it started, and what changed around then — an update, a policy change, a new device
- Scope: which users, devices and networks are affected and which are not
- Which of the steps above you have already ruled out
- Whether it reproduces on mobile data as well as Wi-Fi
That turns a multi-day exchange into one or two replies. If you manage software for a team, keep this as a template.
Frequently Asked Questions
Why does my SaaS app work on Wi-Fi but not mobile data?
Usually a network-level restriction rather than an app fault. Mobile carriers occasionally block or throttle specific ports and hosts, and carrier-grade NAT can interfere with persistent connections. Conversely, if it works on mobile data but not Wi-Fi, suspect a firewall, content filter or captive portal on the local network. Testing both networks is the fastest way to isolate which side is responsible.
Why do I keep getting logged out of the mobile app?
The most frequently overlooked cause is an incorrect device clock, because authentication tokens are time-sensitive and are rejected when the clock drifts by more than a few minutes. Setting date and time to automatic resolves many cases. Other common causes are concurrent-device limits on your plan, expired single sign-on configuration, and aggressive battery optimisation terminating the app's background session.
Will clearing app data delete my work?
It can. Clearing app data signs you out and removes locally stored content, including anything created offline that has not yet synced to the server. Always try clearing the cache first, which is safe, and confirm that offline work has synced before clearing data. On iOS, offloading the app preserves documents and data while replacing the app binary.
The app shows a blank white screen. What causes that?
A blank screen usually means the app loaded but its content request failed or returned something it could not render. Common causes are a permission change that left you without access to that view, a single malformed record breaking the list, a network filter blocking the API while allowing general traffic, or very low device storage. Note precisely which screen is blank and whether others work, since that distinction points directly at the cause.
