Can't playback videos in history

I can't playback videos from my history that were logged since early this morning. There are 3 videos in the history log that will not play back. I can playback videos from last night and very early this morning (around 2am EST) that are logged in my history.I have tried on a couple different phones that were previous setup for our account and fully working up to this point.Any ideas why the most recent videos may not playback? They are from several hours ago, so I would expect them to already have been processed and available.Thanks!
