New Zwifter here. Started the trial last week and everything was working. My setup is PC for Zwift, iPhoneX for Zwift Companion, with bike on classic “non-smart” trainer (Cyclops Fluid) using the Wahoo BT Speed and Cadence sensor (Blue SC Wireless Speed & Cadence Cycling Sensor | Wahoo Fitness) to detect the zPower. Yesterday (May 13th) there was a Zwift software update and now Zwift no longer pairs with the Wahoo sensor. I tested via Wahoo Utility and it’s working in there. I’ve even changed out the battery on the sensor just to eliminate any low battery issue. I just started the month subscription and very disappointed that I cannot use the service with my current equipment. Anyone else experiencing this issue after the software update?
Yes same issue. Speed sensor not working with Zwift Sept 202, but I did connect back in May 2021 so what changed?
Does Swift no longer support Wahoo speed sensor unless you by the blue version?
No reply to your zwift comment back in 2019 so I guess Zwift does not monitor this chat
Yeah, I don’t think anyone is monitoring this thread here 
I’ve since upgraded to the Wahoo KICKR trainer which was more engaging in terms of resistance feedback.
