Credit to AC. Updated my app to 5.30.1 this morning, and it took three refreshes of my bookings, but it nuked all of the flown/cancelled ones.
Still has a couple bookings from my dad's account that didn't get cleared when logging out of it, but that has always been an issue. And those two are a lot less annoying than the 30 flown/cancelled ones.
