Is everyone stuck here?

I quit before I even started lol(?)

Gulp! It's truly a regrettable situation that the performance you prepared with your precious time has stopped, hmph! It seems like a thorough approach is needed, such as checking your network environment or rebooting your device. As a kindhearted piece of advice, if it persists, I hope you'll leave an inquiry through the official channels, hmm!

I can't either.. ㅠㅜ Seems like other people are having the same issue. I really wanted to max out Chitose's 5-star quickly!!!!! It's been two days already.. When will they fix it? Support must have gone to rest after giving us Ensemble Stars!! Music ㅠㅜ

I feel the same way... I think a lot of other people do too.
