What I do in my Global account is download the official apk first, top up, have the new password, install this mod then switch back my account. I don't get banned and I've been doing it for almost 2 years now
Best course of action rn if you don't want to lose your login streak is to transfer your game to an emulator/phone with the official game/apk and your current transfer code (always keep the most current one and keep it safe for emergencies like this) and wait til the modded apk gets updated.
Agreed, I usually plan ahead and take a sneak peek from JP's summoning campaign runs so I can save for a Servant I want (looking at you Muramasa & Oberon) and I hoard summoning tickets like a dragon. Plus, doing Rank Up, Interludes and weeklies give extra SQ.
