I collected all 10, it super charged, I played 1 level and it said "connection issue", please restart or something and it disappeared! There is no connection issue. The wifi and the rest of the game are both functioning normally.
That is happening in my game too! Sometimes, it disappeared after I have fully charged it and sometimes, after I played 5 levels and it's half charged! I don't remember seeing "connection Issue" pop-up though🤔
