SD card showing as not detected after 24 hours

I’m a new Flex user who has been running a sensor for about 2 weeks now. I installed an SD card, ensuring its read/write speed and card storage size was compatible with my Flex. The SD card is detected when I boot up the device, but within 24 hours, according to the online map, the SD card is not detected anymore. When I power cycle the device, the card can be detected again. And then the next day it’s showing as not detected.

Any idea what’s going on and how I can troubleshoot this?
