It happened to me again today, and I wasn't even moving, I stopped recording video, positioned for a photo, took one, then when into settings to take a 3 shot bracketed photo of the setting sun against the mountains, as soon as I hit the photo button, got a black screen.
I figured the gimbal was resetting, but my screen stayed black, switched to video mode, and could see my camera was stuck, it was almost all black, but I could see a little bit of ground to the bottom left. I was using the black plastic sun hood thingy, its like the DJI clear plastic bubble but with a large cut out, and opaque black.

I believe that when it was doing the reset, and gimbal calibration, it hit against the sun shade body and got stuck. Later on,with the power off, and manually moving the camera around, it seems to me that its at least possible, although not common, I never noticed it have an issue.
I brought it back in, while I was coming in, also got the gimbal overload error.
Looked at it and camera was stuck in down angle, removed the sunhood, the gimbal is against all the bands correctly and seated inside the anti-drop covers.
The first time my gimbal reset was after hitting video recording, seemed like 1-2 seconds, this time was instantaneous the moment I hit the photo button, so had nothing to do with sport mode.
I'm not sure if I'll continue to use the sun shade, I like it mostly for a little extra protection around the camera.
Any thoughts?
