Hello, thank you for reaching out to Microsoft Q&A.
May I please confirm whether you have an active Microsoft 365 (Office 365) subscription associated with the account you are using to sign in to the Office apps on your iPad?
You can verify this by signing in here: https://account.microsoft.com/services
Please note that for iPads with a screen size larger than 10.1 inches, an active Microsoft 365 subscription is required to edit documents in the Office apps. If you no longer have an active subscription for the Office apps, you can purchase one here:
