Hello, I've encountered the problem with the D235

Whenever the SD card is full, further recording does not activate. There are no notifications for activity from the camera, and clips that were previously recorded are unable to be played back. Even the live preview feature often doesn't want to display what the camera is seeing.

I've set the device up to be powered.

Recording schedule is 24/7 on activity detected. 

Sd card has been inserted into the device and not in a paired hub.

SD card has been set to loop recording. 

If I format the SD card, all buggy features will return to working normally. It's only when it fills back up again that I encounter these issues.

Sd card details are as follows 

SanDisk 256GB High Endurance microSDXC card for IP cams & dash cams + SD adapter up to 20,000 Hours Full HD 4K videos up to 100 MB/s UHS- Class 10 U3 V30
