My Mavic came back from Service in the Netherlands. Gimbal has been repaired. Try to connect the RC to Mavic. No success. The app show bad signal. Try to switch between 20and 10 MHz. No success. Does it make sense to push the small knob in the Mavic, which is near to the SD card? Thank you for your feedback

This may sound like a dumb question , if so please ignore it - the little switch that's near the SD card is set from wifi to RC, yes?  

Just try re-linking the controller to the AC, what is the signal strength on the controller itself

Hi Hemmet, please ensure the small knob near to SD card slot is set to RC, then re-link the RC to the aircraft, here is the tutorial video for your reference, thank you.
