Help with Garmin sensor 2 cadence and speed

Hi

I have been using these two cadence and speed sensors for three weeks with Zwift no problem. Now today it’s not telling me my watts and I am not moving and cannot start. It says I am moving at x pace but shows no cadence reading anymore

My Garmin sensors are ANT only, how were you getting the BT information into Zwift?
I used to need to go via companion, or a separate ANT dongle. Some HRMonitors also will transcode the signal. I now don’t use them on a controlled trainer with power pedals.
