Certain Line apps(games) not working?

[cAs]

I have this issue that some Naver games (Line company) just don't work. It says: "unauthorized device". Anyone else having this issue? I'd like to know if it's a miui thing or just their fault. Thank you very much

Ok I guess it hasn't happened to anyone XD

For me, I can't play any LINE games at all. I think because MIUI is rooted?

I've tried LINE Wind Runner, LINE Pop, Line Bubbles
