My Tacx Flow was working fine until 2 days ago, when it suddenly stopped calibrating. I can't get it to calibrate in either the Tacx app or with my Edge 1040. The Edge 1040 can't get a power signal. On the Tacx app, there's a power signal but it drops out intermittently, especially if I change gear or the power target changes. I do't lose reistance, although it will change, as if it thinks I'm pedalling too slow or too fast and needs to alter the resistance for my power target. This is making it super difficult to do my scheduled training and fitness tests (and is really hard on my knees).
There are lots of questions around cailbration, but I think this might be a power sensor transmission problem. Is there anything I can do to try to fix this? I have a subscription, which is pretty much money down the drain if my trainer isn't working.
