Bluetooth connection lost on Garmin Instinct Solar

I have Garmin Connect Version 4.36.0.25  on iPhone 11pro iOS 14.1. Many times the green dot who marks an active Bluetooth connection from the app to the watch goes away. 

What I do is go to the settings of my iPhone and switch Bluetooth off and on. Then the connection will work for a certain time.

Sometime I get a red alert message: "Bluetooth permissen requiered. On you phone, please go to Settings > Connect and turn on Bluetooth."

 

  • I went to the App Diagnostics and found the following in the LOG:
