This is stupid – KPOP Amino for K-Pop Review

Every time I try and add a MV to my playlist it keeps saying invalid parameters. EVERY single time. I tried red velvets, twices, Cherry bullets, and many other groups music and none would work. I deleted the app and downloaded it again and still does it. I also checked if I needed to update the app and no updates needed. This is stupid.
