They had me install .27 I haven’t been able to get on the bike since but hopeful the issue is resolved.
There seems to be a few different versions, so guessing they recommend which ever one suits your issue, if they think it’s a firmware fix.
It was weird as I had explained the issue a couple of times and they asked for videos etc. When i mentioned it was like an imbalance in the flywheel they suggested the firmware option.
Hopefully yours can be resolved as well. Have a zwift race tomorrow so should get a good shake down of it in that.
