Im finding that some of my jpeg pics and MP4 (pics) are not viewable in the thumbnail box when viewing inside my local folders. Now if a new pic or video was added to my folder, and it was my first time opening the folder with the new pic or vid in the SLP app, I would get the spinning arrow for a few seconds then the pic shows, but now what happens is the arrow inside the thumbnail spins for a split second then the arrow disappears and no pic is showing in the black box. My pics and videos JPG and Mp4 format. The issue is random. Thanks for any help
