Device & OS
iPhone (iOS)
Scenario
Attempting to restore an active in-app subscription purchase after upgrading from an iPhone 12 to an iPhone 13.
Observed behavior
The application displays an error message stating 'Error restoring. Purchases could not be restored. The process could not be completed.' alongside the code 'AdobeAISSessionClaimStatusErrorDomain Error 8'.
Before you start

Ensure you have a stable internet connection and have both your Apple ID and Adobe account login credentials ready.

Solution 1Recommended

Verify Account IDs and Re-login to the Acrobat App

Ensure your Apple ID matches the Adobe ID to resolve account mismatch errors during purchase restoration.

The 'AdobeAISSessionClaimStatusErrorDomain Error 8' typically occurs when the Adobe account currently logged into the application differs from the Apple ID that was originally used to purchase the premium subscription via the App Store.

1
Check Apple ID

Go to your iPhone Settings, tap your name at the top of the screen, and verify the email address currently used for your Apple ID.

2
Sign Out of Acrobat

Open the Adobe Acrobat Reader app, tap your profile icon in the top right corner, and select 'Sign Out'.

3
Sign Back In

Tap 'Sign In' and ensure you use the exact same email address associated with your Apple ID that holds the active subscription.

4
Restore Purchase

Navigate to the premium features section or subscription settings within the app and tap 'Restore Purchases' to sync your active plan.

Verify Account IDs and Re-login to the Acrobat App
Account Consistency: If you originally signed into the app using social logins (such as 'Sign in with Apple'), make sure to select that exact method again rather than typing the email address manually.

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.
