I'm running v3.9 firmware and my power data has dropped by about 50w. Power Tap have said check the crank length. I check the sensor details and crank length isn't there...

Do others see it on other firmware versions?
Make sure you are connected to the P1 first. I recently switched bikes and had to change the crank length of my P1 while using my 1030. BTW I can't imagine 50w drop is power is due to crank length. More like lost 1 pedal.
The crank length error is linear. By default it should 172.5 mm. If your actually crank length is 170 then you will be getting a slight uplift. 172.5/170 = 101.47 % of the true value.
The P1 in BLE does not combine the data from both pedals into a single channel it requires that both pedals to be paired separately. Most head units and web apps cannot do this, so it then operates like a single sided system.
