Timeline viewer: why do some video thumbnails not show although file is properly converted and available?
All the files I'm using appear to be available in my files library, but when I sync them they sometimes appear without a thumbnail. I even added the file without syncing it to the timeline and got the "converting" timer which also seemed to successfully complete but the file still appears unavailable. (This part I wasn't able to reproduce on video.)
I can annotate said video without a problem.
