Troubleshooting sign-in issues on the B2CORE mobile app

Problem

Clients may encounter various sign-in issues when using the mobile app on iOS or Android, such as:

The Sign In button not responding
Sessions closing immediately after sign-in
Valid credentials not being accepted
Biometric options (Face ID or fingerprint) not working

Possible reasons

Background processes interfering with the app
Expired or corrupted session data
Outdated app version or corrupted installation
Device OS not updated
Cache-related issues (for Android only)

Solution

To resolve most sign-in issues:

Force close and reopen the app

Sometimes background processes cause unexpected issues. Fully close the app from recent apps, and then reopen it.

Sign out of the app and sign in again

If the session expires quickly, manually sign out of the app (if possible), and then sign in again.

Reinstall the app

Uninstall the app.
Download and reinstall it from App Store (iOS) or via the APK file (Android).

Update the app

Check for the latest version in the App Store (iOS) or via the APK file (Android).
Install updates to ensure compatibility and bug fixes.

Check for OS updates

On iOS, go to Settings > General > Software update.
On Android, go to Settings > About phone > System update (or Software updates, depending on your device).
Install any available updates, as outdated OS versions can cause incompatibility.

Clear app cache (for Android only)

Go to Settings > Apps > {App name} > Storage > Clear cache.
