Garmin connect + redmiNote9 + VENU3: BT problem

I tried to update to the last version, but connection losts randomly, and i can't stay with a smartwatch that doesn't work well (no notifications, no calls, etc.)

I returned ti the 4.77.1 and all work well. 

Help me please

But why, my reply doesn't pass the moderation? 

I ask what Garmin's developers changed  in Garmin connect app (android), on the BT connection
