My question -- I share my APPLE ID with another. I am updating my devices and those other devices will eventually updated. My question, if I delete those devices from my account on my iPhone will they be able to link back into my account?
I believe that's true. The older devices will try to upload the old keys in order to sync with the Apple servers in a misguided attempt to get the system to reconnect. I think the only thing you can do is sign the device out of iCloud and use it as a standalone device.
I'm just another user but my understanding is that they will be able to. I have a specific variation on this same basic question, however.
For older (but by no means antique yet) Apple devices like the iPhone SE, whose latest iOS update is 15.7.2, or the iPhone 6 and 5s, whose latest iOS version is still 12.5.6, the Settings > yourusername at the top > iCloud menu does not show the same option to use Advanced Data Protection which appears now (on the same menu) on devices operating with iOS 16.2.
Do we take this to mean that these devices can't be included in the Apple ID account that opts into new iCloud data protection options (until some possible future iOS update modifies this menu to include them)? Thanks.
Advanced Data Protection
