Hello,
Sometimes nico nico singers host live where they sing and talk in live while reading the comments of the people, but for example I noticed that when I liten to Ari's one, after like 15/30 minutes it suddenly stops (while she is singing or talking so it's not because she left) ;_; And when I open thel ink on another window it appears like the live is over.
So I was wondering if someone out here knew why, I don't know if it's because my account isn't premium or if it does the same thing to everyone because of the website, etc. (Sorry for my bad english)
