Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Derek,
For your scenario, please help to check if you log into Windows Store and the account login used for Windows Store has the same username as the one for Office 365. If so, please login out of Windows Store, and then access office 365 portal again.
You may use it or accessing the Office 365 portal in InPrivate browsing as workarounds. Meanwhile, for further investigation, we've sent you a private message to collect some additional information. You can access the private message via https://community.office365.com/en-us/user/conversations.
Thank you for your understanding and cooperation.
