New addon submission page broken (video inside post)

I filled out all of the forms to submit my addon. At this stage in the flow, it has passed upload validation.

Clicking “submit” shows no sign of error (in the UX or in the API response codes). But it also shows no sign of success.

Would appreciate if someone could get this in front of the people who can fix the issue? Thanks.

Please file an issue here with the details. Include the file you uploaded, if possible.
