I have an Epix 2 on version 9.33, and just updated my Pixel 5 to Android 13. Since the upgrade, I've encountered an issue where my watch refuses to sync. I've not exactly narrowed down the cause of the issue, but I think it is new with Android 13. At least I don't recall this issue occurring last week, and now I see it a couple times a day.
Usually I notice that a notification hasn't come through, and when I check the watch it has the ! icon and says that it isn't connected to the phone. If I launch/relaunch GCM, I'll see that the watch is listed as not connected, and the sync arrows will be disabled. If I check the phone's Bluetooth settings, the watch will be listed as disconnected (though items like my headphones will be connected). When I click the watch to connect it, it will fail silently. Toggling Bluetooth off and on hasn't made it work either. The only thing that seems to help is rebooting the phone.
Has anyone else encountered this? Any tips on what I should check to narrow down the cause?
