For some resason the function for Gimbal pitch/yaw will not work on either C2 or C1 buttons.  All other button functions work.  Has anyone had This problem?  It used to work fine. Could it be caused by an app upgrade, or controller upgrade?  Any help would be appreciated.

rceeguy, you are suggested to check if the gimbal speed has been set to zero, please keep us updated if the problem persists.

I don't know if this changed on the I1, but on the I2, now you move the  left wheel while  holding C1 to yaw.

Check the camera gimbal mode on the main screen.  Just below the autotakeoff icon.   Is it in first person view?  I thought I lost my pan function until I realized somehow the camera gimbal mode had changed.
