Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
This is what worked. I didn't think I had office mobile app. It didn't show up anywhere, but when I searched in settings it worked. This solved it:
- In settings search 'office mobile'
- Open office mobile app
- 'Force stop'
- Try to open and will ask for permissions
- Allow all
- Try opening word, excel, Power
Point, etc.
