I received a gimbal wheel error, but was able to move the wheel no problem.  Not sure what it was.

After restarting all devices, it still shows up or not?
May I know the firmware version for aircraft? and what mobile device you are using?
APP is up to date, right? would you please upload a screenshot here?

I kept flying the craft and using it, and it didn't come back.  It seemed to be a one off.
