I don use apple so idk but maybe also need root
This is what AI says
As for facebook, the game devs removed it , not the modders
Alternatively, you can use the clean version to bind your account to a google account first then download unsigned modded version to a rooted device then log in via google
Best is to use a computer for it, recommended emulators are LDplayer for easy root and MUMU12 for Better graphics
