Sorry mate, you got the wrong one :-D This is Kościuszko Mound, not Krak's (which you can see on the attached photo). Yeah, we got at least four of them over here in Kraków :-D
I believe I had an incident like this about a year ago with a Mini 2 (the same controller!). It was scary but after landing and turning everything off and on again the problem never came back.
I have noticed that the DJI Fly got more sluggish and lagging after the last upgrade. (I'm flying the Mini 2, BTW.)
When checking the SD card after a maybe 15-minute flight I found 2 large log files in the /Misc subdir:
fc_log.log 512 MB
camera_log.log 100 MB
The card was freshly formatted just...
Because the panorama is stitched by the app, not the drone. BTW, the DJI Fly app uses only quarter-resolution (2000x1500 px) images, so you are much better off grabbing original DNGs and stitching them yourself.
