I’ve been using Zwift with my Wahoo Kickr Core and Macbook Pro connected via BT.
I have created a few personalized workouts but have problems with them. It turns out that Zwift doesn’t change the resistance in ERG mode. It happens randomly (during first change of FTP in a workout, or sometimes later, it happens when resistance should be increased but also when should decrease).
I’ve read that it may be affected by interference with other devices. But I have turned them off as well as other apps (wahoo Rouvy etc.). I even turned off my Garmin Fenix 6. I use only Kickr, Macbook and Garmin HRM Dual belt (also via BT).
Any idea what I should do to avoid this disappointing issues during workouts? I must add it all works fine with Rouvy so I don’t think it is related to the trainer or Macbook…
