I can successfully connect the watch the first time with the Samsung wearable app. I needed to grant the the nearby permission to play services to do that.
The problem is as soon as the watch loses the connection to the phone, I am unable to reconnect the watch in any way. When I manually reconnect through Bluetooth menu in grapheneos I get the Bluetooth pairing request with pairing number on the watch and phone. Confirming the number and afterwards watch is not connected.
I have to reset the watch to do it again. Any idea? I'm really frustrated and on the jump to factory reset to original rom.
