I was uploading a game yesterday, around 11 hours ago. I already noticed, that it was still in the "unpublished Games" section of my List, even though i clicked on "publish" and it looked like it's published. I thought it may takes a few moments until it will be published. But this Morning it was still in the unpublished section.
Also when i go to "Newest Games", the last game were uploaded 4 days ago, which i think can't be correct.
Going through the Social Media of Scirra also didn't show me some known issues.
