i see i see
i guess it conflict with miui 2nd space feature
in that case u can try the 2nd space feature itself, under settings > storage
After trying XPrivacyLua (and finding out it doesn't work), I feel it's a pain in the *** to keep opening XPrivacyLua and find Singpass app and long press every time I need to use the app.
I've just tried turning on 2nd space, it's another pain in the *** that all settings from my main profile are not carried over, the switching time is not slow but all apps like WhatsApp are considered gone while I'm in the 2nd space.
Too much hassle for a supposed-to-be-quick 2-factor authentication.
I'd rather use the traditional password + SMS than go through all these steps every time I need to login to SingPass or other 3rd party website that offers logging in via SingPass. Or just downgrade to v 11.0.0 and detach.
Too much poking may be dangerous for the next time I want to do OTA firmware update.
