Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
Are you signed in to the same Microsoft account in your Office apps that you used to purchase the subscription?
You can confirm by signing in here: https://account.microsoft.com/services
Does the subscription appear there and is it listed as active?
Are you using MacOS or Windows?
In the meantime, open any Office app, sign out of your account, restart your computer, sign back in, and check if the issue persists.
