I figured it out and it worked! The language is the problem. At first I tried to name the video in Bulgarian (this is Cyrillic) - again and again. Then I named it in English and it worked perfectly!
Then I edited the video from the Red button and changed the name in Bulgarian again.
Here you can see the video: https://d.tube/v/kogitalnost.com/6xi8u52o
I keep my fingers crossed for you as well!
I'm having that problem but ALWAYS use English as my language
I've only had that problem when uploading today.. I thought it was because my cover photo was the wrong size.. I tried everything.. nothing worked..
Have you solved it yet?
Try to log out and back in, also try uploading the snap after the video. those were my two solutions, good luck
