Recently, the resistance during cycling in free ride is all over the place, independent of the terrain. In addition, I can no longer manually shift on the steering wheel. Occasionally this still works for the first few minutes and then suddenly the resistance is all over the place again and switching gears is no longer possible. Please help.
I have a flow fitness perform b3i hometrainer.
I think this is more likely to be your trainer than Zwift itself (I haven’t seen other similar complaints).
Definitely recalibrate if you can and seek support from your trainer manufacturer.

You’ll need to provide more details about your Zwift setup, after ensuring all software is up to date.
