I’ve just updated and attempted to connect my Wahoo Kickr HRM to Zwift.
I selected the BETA choice from the menu and the graphics showed the sensor was active. Mr Squirrel even asked me to wake up my devices.
I waited for a few minutes then started the Companion App on my iPhone. The menu option to use the App was greyed out until the App was running, then I could select it.
Moments later my HRM was connected as usual.
Looks like the current Beta version is unreliable so far but since it’s not possible to pair my controllable trainer and my other sensors separately (ie: Companion app AND Windows native) I’ll stick with the Companion App for now.
