Great game, but has issues

I am the biggest potterhead in the world, so I do love this game. However, it has a lot of issues. For example, I spent money to buy the Avada Kedavra curse, which is supposed to immediately kill your opponent, but I tried it and it doesnt even make their health go down. Also, the multiplayer game doesnt work. I try to do nearby, where my friends that have the app sit next to me and have nearby open, but we dont show up on each other screens, or we do, but its only for a millisecond and we cant click it. Please fix these problems.
