MacBook Pro, Wahoo Kickr V5, Bluetooth issues

Hi Everybody,

I use a MBP, mid 2018, BigSur, Kickr V5, BT connection. I have frequent loss of connection between 10 to 30 minutes into the ride, connection is lossed and does not reconnect. I already did the troubleshooting on the Mac (PRAM reset, BT reset) and also downgraded the Kickr to FW 4.1.2. Does anybody have a fix for me? Thanks. Thomas
