Frequently Asked Questions
Why do mobile apps close immediately upon opening on my iPhone?
Apps usually crash on launch due to corrupted temporary cache files, an outdated app version, or a background software bug. Force closing the app, updating it via the App Store, or reinstalling it often resolves these immediate crashes.
Will I lose my PDF files if I uninstall and reinstall the Adobe app to fix a crash?
If your files are synced to Adobe Document Cloud or saved locally in your iPhone's main Files app, they will not be lost. However, any unsaved files stored exclusively within the app's isolated local storage might be deleted during uninstallation.
How do I force close an app on an older iPhone with a Home button?
Double-click the physical Home button quickly to open the App Switcher. Swipe left or right to find the app that is crashing, then swipe up on its preview card to close it completely.
