Thank you for the tip! I'll give it a try next time I'm in the field; I'll mark your response as the solution if it seems to make my problem go away.
I didn't notice any resetting data, and nothing jumped out at me as missing when I went back to clean up the data from browser, but I guess that doesn't mean I didn't miss something.
All I can find online is that the in-app camera is recommended, but no further explanation. What's the difference between using the OS default camera and the in-app camera?
