Have a brand new Kickr and have it connected to Zwift for the first time today. I replaced a gen 1 Kickr so I know how this works. The resistance seems very difficult - like riding uphill when at 0% grade in Zwift. I contacted Wahoo and they said there may be a compatability issue with the newest Kickr and Zwift. I’m trying to reach tech support at Zwift now. Anyone else have this issue?
Others have experienced issues with resistance. If it was a mainstream issue I’d have expected more to raise it though.
Also have a read here. Potentially it’s a firmware issue.
