I like the app very because it lets the fans interact with the artists but I have one complaint that is. It doesn't provide subtitles for certain channels even if I watch the replay of the live. It doesn't provide subtitles for certain artists like E'LAST, Day6, etc which is quite unfair. Recently, it has been showing error code:0, but my wifi is working to its fullest and I even tried reinstalling the app but it doesn't work. All the other apps are working just fine. I want to fix this quickly.
