Like many others my avatar is unresponsive

*I have a free trial with 25km left
*I’m using an unlisted indoor trainer
*I have successfully connected the Wahoo speed and cadence sensors
*The sensors work on the Wahoo app
*I’m using the Zwift mobile app on iPhone. I have also tried using an iPad
*Zwift is not detecting any speed

What can the issue be?

Thanks in advance
