I still have every deck and collection unlocked, but I can only play white stake difficulty on each of them (except for the black deck where I have just won a red stake and the green stake is unlocked). The challenges are also locked now since the game says I haven't finished a game on 5 different decks. This morning it was fine and I played normally, but I just finished a game and realised I had this problem.
Has anyone else experienced this or know how to fix it? Playing on an Android phone.
