I have the new Calendar layout but none of my activities display on it. The totals are right though, and everything is fine on the activities page.
Also, it did work for a brief period, then the whole site went down; when it came back I have the invisible activities. Huh?
I'm using latest Chrome on a Mac.
This is a little frustrating, Calendar view has been my main navigation hub the whole time, and I'm very happy you're heading back towards the original design (I didn't find the new one much use).
