Paid Microsoft Store submission blocked and Engage Center says No Access

I’m an individual Microsoft Store developer in Australia. My paid Drawing2CAD submission is blocked by the message “You need to update your tax and payout information before you can charge money.”

My tax profile, payout profile and verification all show Complete. The Windows Store App Developer Agreement is accepted, all submission sections show Complete, and the MSIX is validated.

When I try to raise a support ticket through Partner Center, Engage Center displays “No Access.” Could Microsoft Store developer support provide a private escalation route and check why my paid submission is blocked? I can provide my seller and product IDs privately.
