Hi Phoxhunter,
There is currently an issue with logging in to Duet Night Abyss.
Direct email login and Google login (even if they use the same email address) are being treated as separate accounts. Because of this, some users may face problems connecting their game to the app.
If you’re having trouble linking or accessing your account, please double-check the login method you originally used.

I guess the best one can do is just make another account to get said benefits.╥﹏╥

that's right. Google login is authorization through an account Google, A email login is authorization directly through the game itself. these are different options, despite the similarities
