This latest beta Cam V3 firmware has the same issue as the previous beta firmware of 4.36.12.9357 and 4.36.12.9751.
After 30 min of internet outage (not power cycled), the recordings start saving in a randomly generated dated folder with a incorrect timestamp. As a result, you need to physically remove the micro SD card to play it back in a phone or PC. Flashing this Cam V3 beta firmware will cause to act exactly like the Cam OG cameras. In comparison, the Cam V3 stable firmware of 4.36.11.8391 can playback without any problem (under the same condition).
In addition to the Cam V3, it is likely this behaviour is the same Cam V3 Pro and Cam Pan V2 as well. They are probably using within the same firmware branch hence ending in “13.0416”
