Hi Joshua,
I can report that I have repeatedly seen the same problems on our M210 set up as well.
If you look back there a numerous threads on the forums related to similar focus issues across various drone platforms with Pix4DCapture, these date back to at least 2017 and from what I have read on those posts it appears that no additional resources were being diverted to try and address the focus problem. It looks to be a recurrent problem somewhere in the DJI > PIX4D Capture Pipeline, so I wouldn’t hold your breath for a fix coming any time soon.
Here are a couple of examples.

I have been looking at alternative drone mapping apps to use with the M210 to bypass this issue as I cant see any workaround solutions that apply to the M210, can I ask what other apps are which you have used successfully with this drone configuration?
Cheers
