Support case 2609300050004252 unanswered, Engage Center stuck loading: which developer account type for a solo developer?

Hi, On September 30 I opened a non-technical support case (Developer Enrollment in Partner Center), Tracking ID 2609300050004252. I have not received a reply yet, and I can't check the case: engagecenter.microsoft.com signs me in with my personal Microsoft account, but the page stays on loading dots. I tried Chrome, Chrome Incognito and Safari, on Wi-Fi and on mobile data. Could someone check the status of this case or escalate it?

The question from the case: I'm a solo developer in the EU (Romania) without a registered business. I want to publish a desktop app (MSIX) in the Microsoft Store, with paid subscriptions handled by a third-party payment provider (policy 10.8.1).

1. Do I need a Company account under policy 10.14, or can I use an Individual account?
2. If a Company account is required, which registration document do you accept for a sole trader (for example, a Romanian PFA)?

Thank you.
