To try to get a clean start on some issues I've had, I decided to do a reset on my 645M (firmware 6.20). Now I can't get it fully connected to my phone! Garmin Connect gets to the point where it says "Completing setup", I see a Connect icon on the watch face, but when the progress bar gets about halfway across the screen, Connect goes to a screen saying "Paring Failed" with a Retry button.
I've done this several ways, powering down the watch and up again, restarting my (Android) phone, etc. Any ideas what I can do to get my watch back?
