Looks like the gimbal data is missing on the EXIF side on the Mini 2,  GPS and other tags appear to be fine.

That's by design.  DJI was afraid you might try to use the mini 2 with photogrammetery software, so the easiest way around it is to disable the gimbal data.  I'm kidding of course, DJI would never do that.

Thank you for contacting DJI Technical Support.
Our engineer team have checked your issue ,the result of the issue is  that  is normally ,it is from our design .
It is normalyl that the gimbal angle is 0 in EXIF attribute of single photo taken by DJI Mini 2. The gimbal angle parameters of single shot are all 0, and the panoramic photos include the gimbal angle, which is used for synthesis.
Please take it easy ,Have a great fly experience !

Did they ever fix the exif data getting mangled when you saved from the DJI Fly app,   since then I always remove the SD card on the Mini2.
