Welcome to our sweet and amazing community @alexc2671! This seems to be a common issue among many community members. I am going to report this to a CM to see if a solution can be found.
I have either of these problems: 1) I win a quest but the prize notification gives me a message that says I don't have an internet connection. I do. 2) I win a quest and the prize box opens,but I never receive the prize.
