@marni1971 would be able to more definitively answer, but I believe the WW AA malfunctioning qualifies the ride for an immediate 101 shutdown. Some effects are prioritized as "show breaking" in that way.
I'd assume the AA in question with Frozen would qualify as one of those centerpieces under normal circumstances, but in this case given the demand I am wondering if they are eschewing best show practices.
It's highly disappointing because, as you say, particularly given what went into this attraction, it came out rather amazingly - so to already have what seem to be regular problems with what may perhaps be the most impressive part of the attraction is rather sad.
