Sho.co is a method of publishing your videos online without having the render them on your own machine. I imagine that the "publishing" status you're seeing means that the video is still being exported and uploaded to sho.co for your use. I recommend taking export times into account when creating a scribe to be shown to an audience to help eliminate issues such as this, especially as other bugs can happen during export so you can double check for any problems.
