Dont waste your money if you have a personal office 365 account. It will not recognize your email unless it is a work or educational email address. So, you will not be able to use the app. I didnt see anything saying it has to be business subscription to Office 365 and requiring a business email. What a waste of money. Maybe Apple will refund my money.
