Since yesterday - video upload doesn't working.
Vectors and illustrations upload work just fine so it is not "upload limit" 

Anybody else ?

How do you upload?

SFTP

Upload online directly on the site.

Already tried that, not working also.

I have encountered something similar. The ftp server on Adobe works poorly, there are glitches. It's the weekend now, so it won't work even more. I haven't uploaded anything today.
Write them a support letter.

its Uploading system having weird behavior, some videos can be uploaded and some are not?
whats going on?

Still waiting for contributor support to answer.
