Last November 18 I updated GC Android to version 4.25.1. appeared in Play Store.
Since that day, both my FR645 (v6.40) and my Edge 820 (v12.10) unexpectedly disconnect from the bluetooth.
To recover the connection, sometimes it is enough to deactivate and reactivate the bluetooth of the phone, and sometimes it requires turning off and on again the Garmin device.
Any help available to fix it?
