Cadence sensor intermittent, no HR sensor

Hi feedback so far. I’ve switched from 2years of Zwift IOS to Android app. My Wahoo Kickr connects through Zwift app, garmin cadence sensor worked intermittently last night on a training session. The power didn’t work even though NRG mode was activated. Also i can’t connect Garmin HR monitor through the Zwift app at all. Haven’t tried using the companion App. My phone is a Galaxy S8
