Well, I've been playing project sekai since its inception, and it's my favorite game! However, since the 2gb update in April, the game is relatively good for me, but the problem comes at the moment i want to play both solo live and multi live. When I finish playing the song, the game gives me an infinite black screen, and it takes me out of the app. It's really sad, because I love my account on the Japanese server and I don't want to lose it. I've been like this since that update (about 4 or 5 months), and it overwhelms me because thanks to it I have missed many events that I have really wanted to play. I would love to buy a new mobile to play, but I bought this in February of this year specifically to be able to play better, and now I can't afford to spend on a new one :( I hope you solve this problem soon, because it's very disappointing.
