I’ve been using the KickR and Trainer Road for a good while with no problems until today. It shows up that it is paired, but it is not showing any watts. Nor on my Garmin either. I will start pedaling and then all of sudden I can’t pedal because it is so hard you can’t even stand and pedal! I tried to unplug and restart, but the same thing happened. I did a spin-down and that didn’t help either. Thanks for your help.
Sounds like you should submit a ticket at Wahoo Fitness sense this question has nothing to do with Zwift: https://support.wahoofitness.com/hc/en-us/requests/new
it sounds like you’re having trainer issues. I would recommend contacting Wahoo, as they’ll be able to help you on the hardware side.
