AeroPod, PowerPod and Newton

I have the "front mount" setup". Last time I used it, it was already 3 year ago and was perfectly fine.

I have the "PowerPod" letters parallel to the floor

I tried 2 calibration rides, which took only about 3min the hole calibration ride, eve tho I had "best precision" setting, and I cant get normal values. It seems like most of the time the power values are just registering 0 and sometimes "it turns on" and give some normal values,...
