Using Samsung Galaxy S20 for Companion App.
Companion app is paired with Zwift running on Apple TV 4K. Works fine for Bluetooth enabled sensors but not Ant+.
If I use the Zwift app on the same phone, Ant+ sensors are correctly connected to. Used a 3rd party app on phone to test Ant+ connectivity (ANT+ Plugin Sampler) and everything works fine.
Tried reinstalling Companion app and reinstalled Zwift app on Apple TV.
To summarise:
Pair from Apple TV to Companion works
ANT+ sensors fine for other Apps on the phone
Yet companion app doesn’t make them available to the Aplle TV app, just Bluetooth.
