I also just emailed my rep McKenna about the ticket trade-in/exchange. I'll see if she has any updates or if I hear back from her.
McKenna got back to me this morning saying the trade-in is going live today/tomorrow, and I can make my purchase then.She's the same one I emailed on Saturday about the same items and I haven't heard anything.
There is somewhat limited ticket availability right now. That might be because they are holding some back. We will see.
