Reset End to End Encrypted data will not go away iPad mini 5

Hello Stewartfromtoronto,

Thank you for using Apple Support Communities. Based on your post, you're receiving an error to 'Reset End to End Encrypted Data." We'll do our best to assist.

It sounds like this is about iCloud encrypted data. We'd ensure the device is up to date (first back it up): Update your iPhone, iPad, or iPod touch

Note: If you do reset this data, will will be erased from iCloud, but not from the device itself.

Address any notifications for 'Update Apple ID' in the Settings app.

Set up a passcode to see if that helps out: Set a passcode on iPad

If the issue persists, then it might be best to Contact Apple Support

Wishing you the best, take care.
