Data Types wasn't showing up on the Data ribbon so I added a new group and added it but when I click on it nothing happens. I contacted support through chat and he wound up accessing my computer remotely. We tried Excel in safe mode, checked the add-ons, ran a repair and updated 365. This is on my personal Office 365 account and I'm having the same problem on both of my computers.. I have a monthly subscription my editing language is English.
