Warning to those with AirTags. Mine are gone from Find My. When attempting to reset one of my working/paired tags before the upgrade, I get a Bluetooth error when trying to set up. So all of my tags are dead right now and will not connect to my phone. However a friend who had one of my tags for a couple of days gets the notification that my tag was with them and to tap to contact the owner.
