I have the same problem. I was filling the submission Windows & Xbox app several days ago, and now I cannot access my product I created. https://partner.microsoft.com/en-us/dashboard/products/9NMFQ1JTWHSM/overview
It shows my account is deactivated
I try to revisit the whole process, go the directory https://partner.microsoft.com/en-us/dashboard/directory, and getting started for Windows & Xbox
the partner center tells me I don't have permission to the url https://partner.microsoft.com/en-us/dashboard/registration/AccountInfo
I cannot finish the app submission now. What should I do?
