Found the solution regarding missing smart notifications, at least for me. Open your phone settings, and search for "Notification Access", and make sure Garmin Smart Notifications is enabled. Even though i had the pop up within connect to request access it seems like it was never actually being allowed within the phone system.
E2A - It was actually a Garmin youtube video that showed me the answer... https://www.youtube.com/watch?v=YSOOAxxceJ4
Hi, I also have a problem with my Vivoactive 3 and a P30. In the beginning everything worked fine but now the watch does not reconnect when I turn off and then back on bluetooth.
I always have to reset the watch to pair it again then which is of course not a good workflow. Trying to pair without a reset only shows a question whether I want to link the watch but no PIN comes up.
Tried and gave Garmin Connect already all required permissions and switched off the power managrment.
