From time to time I have an intermittent issue with the device not being able to find an SD card even though the SD card is in the slot. I'm using Patriot Class 10 32 GB chips. Sometimes all I have to do is take out the SD card and reinsert it back into the Device and that helps, but a couple of times I had to use another SD card. Has anyone else had this issue as well?
