IMessage keeps signing out on iPhone
I have a recurring error whereby iMessage on my iPhone SE (running IOS 15.5) keeps signing out on its own. I get an error message telling me this has happened and prompting me to sign back in, which I do, but in the meantime messages don’t sync properly between my different devices (iPad, Mac, watch). Is there anything I can do to stop this from happening? Thanks
iPhone SE (Gen 2)
