Frequently Asked Questions

Why did my PDF reader suddenly start freezing after updating my iPhone?

Major iOS upgrades like iOS 12 introduce new system architectures that can conflict with older application code. These compatibility issues often cause apps to hang on launch until the developer releases a dedicated patch.

How can I check which version of Adobe Acrobat I have installed on my iPhone?

Open your iPhone's 'Settings' app, scroll down the main list until you find 'Adobe Acrobat', and tap on it. The current version number (e.g., 18.09.14) will be displayed on the settings page.

Will I lose my saved PDF documents if I delete the freezing app?

If your documents are synced to Adobe Document Cloud, iCloud, or saved in the iOS Files app, they will remain safe. However, any files saved exclusively within the app's local storage without cloud backup may be deleted during reinstallation.
