Youtube app is not working

I am also having a problem right now where the Youtube app isn't uploading videos. It was working fine two days ago when I last uploaded a video to YouTube. But sometime later, the app wasn't able to upload. When I selected a video to upload, the app showed
the progress bar of the video uploading, then the app informed when the upload was 100% complete, but when I went to my YouTube video manager, the video would not appear. My YouTube page would say the Upload Failed: Cannot process file. I also noticed that
the YouTube app on Xbox was suspiciously uploading a 9 minute long video too fast. Normally when I upload a video that long, it takes a while, but when this error occurred, the YouTube app was speeding too fast to be believable. Maybe that has something to
do with it.
