Messages loses connectivity and requires restart
Messages keeps losing connectivity and has to be restarted. My iPhone is on the same desk. A message (from "blue) Apple user) comes into the iPhone but (very) often and not transferred to the iMac (Tahoe) for several minutes and sometimes not at all. I have to quit messages, start it up again, and then send a message to the person whose text did not come through. That restores connectivity.
