So I've been having issues with itch.io the whole day, including right now on the upload of the game and submission to the game jam. I'm trying to submit and it says "invalid game", as well as a bunch of issues on uploading images and gifs on the page. Are we having a submission deadline extension or something like this?

I'm having those issues as well. Sometimes I can't even load Itch. Third party outage trackers are reporting other people having this issue with itch since this morning.

Yeah I am having some issues with trying to update cover art and such.

Same here having major issues with uploading screenshots, cover art, and logo.

Hi. We had a deadline extension yesterday due to bugs. It does seem like there are still intermittent issues. If you miss the deadline due to major technical issues, let us know and well try to help you. At this time there are no further deadline extensions, but we are monitoring the situation. Thanks.

Having the same issues, can't seem to upload builds, screenshots, cover art and logo as well

It happened to me earlier, had to wait a little for itch to calm down
