A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi! My name is Aj and Im an Independent Advisor here to help! If you bought the Microsoft 365 Personal through your Apple ID like via the App Store, you should try restoring the purchase again by signing out of the app completely, closing it, then reopening and tapping "Restore previous purchase" at the bottom of the Get Started screen.
But if that keeps failing with the "something went wrong" error, this is probably something Apple needs to handle since they manage the billing and in-app purchases for stuff bought on iOS.
