Garmin venu 2 disconnect

Garmin venu 2 and samsung 23 keeps disconnecting and goes I to pairing mode every time I restart phone or move away from it, and I have to restart setup and sync. I searched all forums, tried to run permission all of them and also run in background. Restarts, resets, nothing works. Watch, does not work on Samsung s20 either. How do I fix this?
