Don't read SD card sometimes

A few times I have looked for files on my SD card via s2400 as I go thru folders, I got “no files” screen, I press back then go back into folder and files are there.

Yesterday I was looking for a file, it said “no files” I tried same thing, but this time there was nothing. I tried afew times, then had to turn off S2400 and restart it. The files were back there.

This issue never happened to me before the last update.

Has anyone else experienced this?

Have you tried using a different SD card to see if the issue is still there?
