Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I am having Micosoft To-do IOS sync issues as well. What is unsettling is that it is inconsistent. I happened to notice a few todos on the Windows 10 app that were not showing up on my ipad app. However, changes were showing up on my Android device. So it just seems to be the ipad that isnt catching all changes during sync.
Most of the time they all seem to sync fine, but it is disturbing to run across a few outliers and realize you dont have everything synced.
