Can you try going to Sessions by Day, selecting Tues., then Tuesday Morning Keynote, and click Added (calendar icon near the middle of the screen)?  Then go back to the app home page, click the hamburger nav. top left, click My Schedule and select the day. When I follow these steps, I see the sessions in My Schedule.
