Frequently Asked Questions

Why does Acrobat show an application error when I try to subscribe on my iPad?

This specific 'Unable to complete request' error is often caused by a backend server issue on the developer's side or a synchronization glitch between the app and the Apple App Store's purchasing system.

Will deleting and reinstalling the Acrobat app fix the subscription error?

It might help clear temporary cache glitches. To do this, long-press the app icon, select 'Remove App', and then download it again from the App Store. Ensure you have backed up any locally saved PDFs before deleting the app.

Can I subscribe to Acrobat via a web browser instead of the iPad app?

Yes, you can often bypass in-app purchase errors by opening Safari or Chrome, logging into your account on the official Adobe website, and purchasing your subscription directly there. The subscription will sync to your app once you log in.
