Apple just replaced my six year old battery in my iphone 7 Plus (iOS 15.7.2). Now I see this new imessage “IMessage <Date> <Time> You left the conversation.” It appears in some messages but not all. My ipad and iphone 12, which receive the same messages / emails do not show this iMessage.
Other than the new battery and Apple turning off the “Find My” app before doing the work, no other changes were made at the Apple store as far as we know.
My question is this: How do I locate and turn that imessage off?
