I believe you can purchase them at the theater now.
You can do both but honestly I prefer to buy through the app and have them scan it it's much faster and smoother that way
Yes you can by tickets at the theater.
I recently went, and I purchased ahead online but saw others buying tickets inside. I'd suggest buying ahead only because it's assigned seating and most times by the time you get there, all the good seats could be taken. ESPECIALLY if COVID guidelines are still in place. Hope this helped!
