default session length

This is the same for me - what has happened - only 30min meetings!

I figured this out. I thought the Start and End time had disappeared. They have changed it so when you click the blue Schedule button, on the next screen under the All Day button it shows two entries for today with drop down menus for times. 

The top date is the Start Time and the second date underneath is the End time.

A bit like if you are booking a hotel with the check in date and the check out date. 

Except that you are scheduling the same day, just the start and end times are different.

Weird way to do it, I know!
