I have a 9th generation iPad with iPad OS 18.1.1. Whenever I go to the Hearthstone store to buy packs it almost always crashes. I also frequently have crashes when I’m editing a deck. I occasionally have crashes mid-game too, but that is much more rare. I suspect you have various buffer overflow bugs causing these crashes. When I use my iPhone 12 Pro, which is on iOS 18.1.1, I don’t get crashes like this in the store.
