I just went through the whole process again since I never got an actual confirmation email for my initial purchase. In doing so it took me to the oogie boogie queue.
I closed the Disney App, closed out of the browser windows, switched from Wi-Fi to 5G. Opened the Disney App, selected Tickets and Passes, Selected Special Events, Tapped Select Tickets, Picked my quantity, date, and entered names, selected payment and this time right away I have tickets showing up in my app and a confirmation email.
