Messages don't mirror between iPhone and watch
I have an iPhone (XSMax) and Apple Watch (series 5). Both are up to date on the OS. I have Messages turned on in my iCloud account. Even though I have Mirror iPhone checked on the Apple Watch OS, it doesn't. When I delete a message from the iPhone, it doesn't delete from the Apple Watch. Many of my messages are just one time access codes as I have 2FA turned on for a lot of my online accounts. So texts just accumulate on the watch and then when you try to delete them, you can only do it one at a time from the watch unlike the iPhone where you can select edit and do many at a time. I am tempted just to turn off Messages on the Watch but can't figure out how to do that either.
