Frequently Asked Questions
Why does Acrobat show Error 8 when restoring purchases on my iPhone?
This error generally indicates an account mismatch. It happens when the Apple ID used to purchase the premium subscription via the App Store does not match the Adobe ID currently signed into the Acrobat app.
Will I be charged again if I tap 'Restore Purchases'?
No. Restoring a purchase simply prompts the app to communicate with the Apple App Store to verify your previous transaction. You will not be billed again for a subscription that is already active.
Can I transfer my App Store PDF subscription to a different Apple ID?
No, all App Store subscriptions are strictly tied to the specific Apple ID used at the time of purchase. They cannot be transferred to a different Apple ID.
