Having a slight variation of this issue, except involving Messages in iCloud...
Here's my devices:
Mac: macOS Monterey 12.6
iPad: iPadOS 15.7
iPhone: iPhoneOS 16.0.3
Whenever I delete a single message, or an entire message thread, using the iPhone, it immediately vanishes from all my other devices, as intended.
Whenever I delete a single message, or an entire message thread, using the iPad or Mac, it will NOT delete from my iPhone. Deleting from iPad will delete thread on the Mac, or vice versa, just not the iPhone.
It seems as though there is a bug in iOS 16 where in Messages, requests via Messages in iCloud to delete message(s)/thread(s) from other devices running previous-generation OS's does not work anymore.
To make sure it wasn't an iCloud issue on the iPhone, I did the following:
- Signed out of Messages and FaceTime directly via Settings -> (respective settings)
- Disabled iMessage / FaceTime after signing out
- Signed out of iCloud completely, and deleted locally stored data
- Shutdown / restart iPhone
- Signed back into iCloud
- Allowed device to sync, and repeated deletion tests
The results were the same.
Anyone else having this?
Cheers
