Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi!
In the Azure portal, open Microsoft Entra ID > Users and check whether your account is listed there. Also check whether it is shown as a Member or Guest user type and if it has administrative roles assigned.
You can also try to create a new user in Entra ID, give it an administrator role, and use that account to sign in to the Microsoft 365 Admin Center.
