Bug or feature?
Planner sometimes doesn't update the description of a card after some user has changed the contents of said description. Maybe a "save" button or a pop up that tells you if it is applying the changes you made once you click out off the card would be in order. I know the Sync proccess isn't immediate, but with no way to tell if what I wrote will stay it's somewhat hard to convey important information about a task reliably to my colleagues.
If this is native to Microsoft Planner itself then I'd like to know if maybe their Support has some type of reporting or suggestion feature.
