For what it’s worth, I’m having the issues regarding the alerts and the SD card events on the V3, as well as my V2’s, since upgrading to the 2.16.14 app. Android 11 on an S20, with Samsung Pro Endurance 32GB Cards.
All events throw an exception error, either 04, or 07, and I cannot access my recordings, although the events show up. I initially tried reformatting the cards, but the issue arose again. I then force stopped and reloaded the app, and all was fine. Problem is that the issue comes back after a day or so.
Seems like (at least for me) more like an app problem than with the cameras, particularly since the V2’s are affected as well.
