Garmin HRM Pro dropping out since update

Since the update my Garmin HRM pro drops out when entering the world. All is fine when at the pairing screen, connected. Showing a heart rate. Enter the world and no heart rate. Menu back and go to pairing and it reconnects and shows a heart rate. Go back to the world and it’s gone. I do this a few times and eventually it stays.
Running Zwift in Apple TV.
Anyone else having similar issues?

See the bugs and support section ( I can’t post links yet)

Since the last update there is an issue with the stability of Bluetooth.
