Today while I was flying my Inspire 1 with X5 camera, I was unable to change aperture on DJI GO. I was in aperture mode and tried changing into all manual and shutter priority, and nothing worked. It was stuck in F4, but I was able to still change ISO and shutter speed (in manual and shutter priority). I brought the drone down, turned it off and back on, and the problem was resolved. Two more flights were fine. Hopefully this doesn't happen again, but I thought I'd post this in case anyone else has seen this and/or has any ideas. Anyone seen this happen before? Thanks.
