I think this is a bug?
From Plan > Calendar
If I scroll ahead a few months, and don’t see my event, I realize I need to click on “All Events” to see it. When I click on “All Events,” I get kicked back to February (current month). Then I have to click ahead to the month I was looking at just moments ago to see “All Events” for that month.
My expectation is that clicking on “All Events” will show me all events for the month I am currently looking at.
