For a couple of weeks now my watch hasn't connected to my iPhone. A few days ago I managed to get it to connect following the troubleshooting steps, but then after a half hour or hour while I was updating which information I wanted tracked and available to view on my watch, it disconnected again and so far none of the steps I've followed has been able to reconnect the watch. I've even reset the watch completely and signed out and deleted Garmin connect.
Very frustrating with two very expensive gadgets not working together. My Bluetooth works fine and as expected with my Bluetooth earbuds and my car. So can't be fully on my phone.
