Received this from Wahoo - Don’t run 2 apps with Kickr.

The KICKR was designed to only be controlled by one app at a time. If you’re running more than one program simultaneously, this will lead to difficulties and odd readings as these fight to control the KICKR. Our app will have more power smoothing built in to it, so your power file might not show the highs and lows. Although, the averages should be pretty close. In this situation I would imagine that something was causing some interference. I would suggest performing a spindown calibration once every few weeks. Also if using Zwift, please make sure the Fitness app is closed to ensure you are getting the correct readings.
