I believe I’m having the same problem as in first post. In ERG mode the power doesn’t change when it’s supposed to. The target power on the screen is going up or down but the resistance won’t change.
I have been using TrainerDay about two months now and there has been maybe two sessions at the start when this did not happen. Lately it’s been happening in every workout and usually it happens on first or second interval. Nothing else seems to fix it but to turn bluetooth on phone off and on, but it’s just a temporary fix, same thing happens again in the next or maybe second interval. I have tried pressing - / + buttons on screen, reinstalling the app, disconnecting other bluetooth devices or shutting them down, changing phone position and whatnot but these haven’t helped.
I’m using Toorx srx 3500 spin bike, Oneplus 5t (tried it with oneplus 7t but it did not help) and Polar H10.
