I am experiencing the same. Sho didn't issued the link to video I recently uploaded and after so many hours, that video is not even rendered yet.

If you are experienceing an issue with a Sho.co upload please log a support ticket via https://help.videoscribe.co/support/tickets and include the shortlink to your video. We can then take a look at it's progress for you.

The thing is that I didn't get a shortlink. When it appears that "Video is published on sho.co" the link portion was empty and I didn't even get the follow-up email they send normally.

Video is published on sho.co is a confirmation the video has published. 

You've published it as Private though so you will need to log-into Sho.co and click on 'My Videos' to see it. You will not be able to see Private videos unless you are logged in
