Garmin Connect connection troubleshoot notification issue

Hello Community

I have curious notification issue on my phone. 

I have my clock turned off for personal reasons for last few weeks
Garmin connect persistently sends notification about Bluetooth troubleshooting each day in very early morning which sometimes wakes me up. 
What is especially irritating that this audible notification ignores "do not disturb" schedule on my phone. Also i was unable to find a way to disable it.

To resolve this i tried following:
- Reboot my phone
- Update the Garmin connect app. 
- Disabled following option in phone: settings - apps - app managment - garmin connect - manage notifications - Allow in Do Not Disturb
- Disabled following option in phone: settings - apps - app managment - garmin connect - manage notifications - Device Connectivity

Rest of the notification options are set to ON

In Garmin connect app itself under Settings - Notifications - App Notifications - "Follow Do Not Disturb Behavior" is set to ON

I am using Vivoactive 4 with Android phone One plus 12R
Android version 16 Soft: CPH2609_16.0.3.500

Garmin connect version 5.23.1

Any help is appreciated.
