Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
Please try signing out of OneDrive and then signing back in to refresh your account status.
If the issue persists, could you please check whether your storage is updated when you sign in to OneDrive on the web?
Since it has already been more than 48 hours, if your storage still has not been updated, I recommend contacting Microsoft Support directly so they can verify your subscription or license and investigate why the additional storage has not been applied to your account.
