The concert was amazing! But the ticket purchasing process was awful- trying to purchase a combination of adult and kids tickets meant I had to individually select seats and use the drop down menu for ticket type, but when i did this, the tickets did not get locked in place (i.e. secured) for me so as i was doing this the tickets kept disappearing. Very frustrating process. There should be an option to preselect type of ticket and then look for Best Seats, or preselect your seats, so they are "reserved" for the few minutes, and THEN be able to select seat type after the fact, once your tickets are temporarily locked in place.
