Garmin FR945 asking me to pair almost everytime I use the watch, or asking to pair again the next day.

Pretty much the subject sentence. I pair the watch, it works, uploads workouts etc. After a few hours or the next day, the watch will not get notifications and when I open the Garmin Connect App it will ask for pairing automatically, which I do and restart the process all over again. I tried resetting the watch to factory settings, deleting the app, re-paring (obviously), nothing works. I have a FR920XT which works flawlessly, as well as other Garmin products which also work,  so I know it's not the phone.
