Apple TV, Wahoo kickr core, ftp test

Just bought the kickr core and using with Apple TV. I recently did the hour long ftp test through zwift and my wattage was fluctuating Between 220 to 330 every second during 20min test. Does anyone know how to solve this problem as I could gauge a accurate wattage i was riding at?

Same happened to me, feel slightly broken after 20 minutes of “guess the wattage”, tried setting power on my element bolt but had the same issue, am either cycling squares or something’s up, if anyone from Wahoo is watching the forums please help. I run the kickr core with a PC and ANT connection (via USB extension so sat right next to the trainer).
