Somethings wrong – Piano City - Spring Music Festival Story Review

There is something wrong going on. I tried visiting my favorite old game and then it says to upgrade it?? I looked in the upgrade section and I didn’t find the game. And then after that pop up i go back and it says I don’t have wifi but I do. If anyone else knows what to do please help.
