Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Vicki,
Another way of changing your subscription manually is to go to https://account.microsoft.com/services sign in using the account tied to the subscription. Find your current Microsoft 365 or subscription listing, select Manage, look for an option labeled Upgrade, Switch Plans, or Compare Plans.
I hope this answer is helpful if you have further questions feel free to reply back
