I had the exact same issue with my 522GW. After a lot of reformatting, reinstalling etc to no avail, the "issue" seemed to be with the app (iOS). At first I didn't see it, I had a bluetooth connection to the phone, paired and everything was working, it was continuously recording.
However, during some driving sessions, it started recording and right up until it paired with the phone (anything between 10-30s) it stopped recording.
Turns out that if I had used the app after the last driving session and entered the library tab to download some videos, the app would remember this and default to the library view, even when I hadn't started the app manually. As you might know it will also automatically stop the recording on the dash cam when in library view. This was even though the app was only running in the background and it could be several days ago since I used it actively.
Every time it stopped recording upon connecting the bluetooth. So I would say it is more of a design flaw and suggest that it only stops recording when actually using the app.
