Used to see power and cadence via 965, now only cadence shows, power is always zero. Power shows on my cycling computer and on Wahoo app, the pedals appear to be fine and sending a signal. I've removed the sensors, added them back in, restarted, turned on/off, calibrated. I rode at least 10 rides with it working perfectly, now it's gone. Any suggestions will be greatly appreciated. Obviously, they connect because I see the cadence info. Why is only power gone? Thanks.
