New Partner Signup for Company Stuck in catch 22 loop

I'd like to second this detailed reply. I at least have the "Resolve" button.

Last week I clicked the resolve button and uploaded the latest invoice for the company website domain. The error/warning message says "Pending partner action", but I did take the action specified (uploading the document). Now I'm not sure if:

1. My first document was rejected - there was no email or notification saying that it was
2. I need to upload a different document. I have no way of knowing if/why the first document was rejected so it's impossible to know how to fix the issue
3. The first document wasn't actually uploaded - the account verification sidebar showed that it was, but I didn't get any email confirmation and there's no audit history to show that the document was uploaded

So now I have no idea what to do and I'm not sure what this ominous date "Estimated date by 4/4/2026" actually means. Does that mean someone at Microsoft will review the issue by then? Does that mean the application will permanently close at that date? Does that mean Microsoft will send me a present by that date?

Any clarifications from the Microsoft team would be much appreciated.
