We’re currently working on defining a compact mode experience. I will post more details when we have more to share.
Thanks to everyone who volunteered for testing the Office 365 group calendar. The TAP team will be reaching out as we are closer to being ready.

This seems like it should be basic functionality - you get a calendar with your Team, so why should you have to pull up a different app to easily use it? Hopefully this is getting some priority.
