Hi,
Yesterday 24th Sept my partner's Garmin 45s received an update.
After that happened the watch is connected and receives notifications from the phone (e.g. strava kudos).
Unfortunately now it would not sync over bluetooth (sync workouts over cable still works)
During syncing in connect app the syncing arrows rotate, but the circle round the device icon does not start its journey round.
The Watch "About" menu reports 5.10 but given its been out so long I'm not sure it was that.
Its iOS 15.6.1 on an iPhone SE.
I tried several things, neither worked:
1) removing it from phone/bluetooth and connect app and rediscover (twice)
2) factory reset, removed again from phone/bluetooth and connect app, rediscover.
3) removed/reinstalled connect app
Update: #3 looks like it worked, it just took several hours to sync.
Many thanks
