Tried Zwift today and can’t move out of 6th gear on my Wattbike. I have downloaded the app again and paired everything and still the same
There was another reported issue of the same type:
The rider states they were able to solve it by “I had to reconnect the shifter over Bluetooth.”
Have you tried that and did it help/solve? I can see you mentioned you tried repairing but did you repair the shifters in particular? Might be worth messaging the rider from the above thread to find out exactly what they did
