So, I bought a ticket for a Sunday event an hour or so ago; it shows in my transactions and under my name, but the event doesn't show on my schedule. Should I be concerned?

No, it's taking a while for the Schedules to be updated. It'll show up later. The push of Wishlists is done, so things should be getting updated faster, now. 
 

Is it an 'electronic ticket'? I don't think those show up under My Packets.

I ws looking for it on the schedule, not the packets. But it did show up now! Thanks all!
