I'm not 100% sure myself but I have heard people say that the modded apk for the game is only 32-bit, rather than 64-bit which the vast majority of modern phones will support. It might be more difficult to modify the 64-bit apk, which is why the 32-bit apk is used.
Even so, I'm concerned we're reaching a point where the 32-bit apk is no longer viable. There's a 50% chance that booting the game will result in an instant crash before I even make it past the loading screen nowadays. It never used to be this bad. I think G-Bo's gonna have to bite the bullet and find a way to mod the 64-bit version sooner or later, or else we're not gonna be able to use this mod anymore...
