Does GO4 support FPV view along with a single gimbal camera on M200 series?  I thought it did.  It works fine with Pilot but when I used GO4, all I got was an FPV frame without video.  Main gimbal camera displayed fine.  When I went back to Pilot, FPV worked fine.

Yes, FPV works with GO4 and single gimbal. Am i assume right, that you are operating with Crystal Sky? If so, try to reset the CS to factory defaults and try again.

Yes, I am operating with CrystalSky. I’ll give it another go and see what happens. Thanks for the info. I’m glad I wasn’t imagining things about it working in past!

Keule is spot on. Please make sure you do not turn off the FPV in DJI Go 4 app and keep us posted on the latest progress, thanks!

I am pleased to report that it is working, though the FPV tears a bit while UAS in motion.
