I'm unable to log into my Hogwarts Mystery account through this APK. I'm using the most recent version of NOX and the latest Android version. If I have the facebook app enabled, I get an error that says "Login Error: There is an error in logging you into this application. Please try again later."
When I disable the facebook app (as suggested for facebook account login in the OP), I get a different error that says "For your account security, logging into facebook from an embedded browser is disabled. To continue, download and log into the facebook app on your device and try again."
Is there something I'm doing wrong? How do I access my previously saved game through this APK?
