i upgraded my wife’s iPhone X to 12. Ever since she’s missing messages. Some show up, some don’t....unless she manually shuts down the Messages app and restarts it. Then the missing messages suddenly show up. For awhile until they stop again. Then, a restart of app and they show up again. Maddening. Even weirder....she will get new message notifications on her series 2 watch, but these same messages won’t show up in Messages app until/unless she restarts that app. Anyone else having this issue?
