I just bought a used Tacx Bushido it is not calibrating with Zwift, it is impossibly hard to pedal. I reduced the trainer difficulty to no help. I have tried to use the Utility app to to no help, my speed gets up to 18km then starts going down. Any suggestions on how to get it working properly.
I have updated the recent firmware: 3.1.22 / 3.1.10.
