Sd card cannot be formatted or cleared. Tried in a computer, erased all, put into wyze cam and still reads full memory. Will not let you watch playback. I used to be able to. Firmware updates constantly but 50% of the time it won't update even over wifi. I'm not going to buy a new SD card every time this happens and would be happier to put the cam in the trash at this point. Zero feed back from wyze. Why won't this just be consistent? Buy bananas and get monkeys.
