This app is completely broken. I am a brand new player on it and can't even finish the colored first missions to unlock the decks. I am at the 5th level of every one of the decks and it won't allow me to challenge, saying "network error try again later." It's literally impossible for me to even play the game. I bypassed the missions but can't even play against anyone. Worst experience I could have gotten. Contacted support and received. No feedback as well. Don't download if you're new.
