I personally use a Sandisk, many have and been disappointed, it needs to Class 10, U3 suitable for video, High endurance Sandisk would be my recommendation but only buy from a reputable seller, there are many fakes out there.
Okay so rear is not connected, (by choice or not working?), so each 3 minute recording is storing 6 mins of playtime, enough for around 3 hours of storage before it loops again. Bare in mind you will never achieve the stated storage as that’s how they work/ programmed.
Below is a full reset as provided by Millie at Nextbase, I have basically copied and pasted. It may help. A bit more than just pressing the reset button.
The latest FW update is R23.7, you say you have that. Good luck give it a try.
