I've had a lot of issues with deleted messages not deleting across all devices. All are up-to-date with the latest OS.
I’ve noticed this too but only very rarely majority of time it works well
Maybe log feedback with Apple on the feedback websiteIt seems to delete correctly more frequently when I delete from my iPhone. If I delete from my iMac or MacBook, it doesn't delete on my iPhone. I've turned it off/on, signed out, logged back in, rebooted, etc. Still not working properly.
That’s good. Yes I’ve noticed this too on the Mac eventually they did show but took about an hour I tried turning off messages in iCloud and back On again that seemed to have helped. You may need text message forwarding on in message settings I wouldn’t imagine you would but just have it on in case see if that worksIt takes several days for all messages to initially sync.
In my experience it's always been a bit flakey. I've used it since 11.4 day one, and updated to all iOS versions/iPhones to be released since then - consistently, up to and including iOS 15, I have had messages reappear that I'd previously deleted. I also will still have messages and attachments take up phone storage as well randomly, and I still haven't worked out exactly how it decides what is stored where or how to change it.I either missed this or decided not to turn this on years ago. Tonight I was backing up my SE in preparation for turning on my new Mini. I realized Messages was not turned on in iCloud and turned it on, not realizing it was a later feature. I kind of thought it got turned off on a hard reset this past spring.
I haven't run out of space in iCloud but I now have about less Message space showing on the phone. I won't burn myself by turning it back off later? Has it been improved since 2018?
The whole thing can be a little weird. As I said, I've never used it before yet in upgrades and phone replacements, my messages have always come over.In my experience it's always been a bit flakey.
