I connect my s60 to my Samsung s21 like it says in the manual,it goes through and connects fine. I set my watch up how I like it with the yardage,vibration type,watch face etc,it works great for golf and notifications steps etc and I love it.
Then after a few hours I stop receiving notifications alerts and calls on my watch,I try to sync it but again (it says syncd) but still doesn't show notifications.
So I have to reset my watch delete my device from the app,unpair my Bluetooth and clear my cache from the Bluetooth app on my phone.
Then go through the setup procedure again.
Love the watch but it's annoying
