What happened?
Preconditions:
- User is logged in with an active session.
- App is sent to the background and left idle long enough for session timeout (approx. 15 minutes), but before the OS terminates the process under memory pressure (jetsam).
Steps to Reproduce:
- Open the app and navigate to any active content screen.
- Send the app to the background (swipe to Home).
- Wait ~ 15 minutes (long enough for the app to suspend).
- Tap the app icon or select the app from the App Switcher to bring it to the foreground.
Expected Result: App transitions cleanly to active state, refreshes necessary session data, and renders the current view hierarchy.
Actual Result: The screen renders completely blank/white/black. The UI does not populate, and user interactions do not register until the app is force-closed from the App Switcher and relaunched (cold start).
Notes & Isolation:
- Cold launch (after force quit): Working as expected.
- Immediate resume (a few seconds after backgrounding): Working as expected.
