We submitted our Oculus GO game a week ago. The shutdown is right around the corner. Our app hasn't been approved yet, and I have a substantial app update I need to submit, along with new screen shots and a video. I can't update the app until it's approved, and I can't cancel my submission in order to update and resubmit. It won't let me cancel the submission for some reason.
So, there's absolutely nothing I can do at the moment. With the shutdown 4 days away, this is very worrisome.
