It was impossible to use Pokemon GO during Halloween, so you will need to connect it again. It was fixed by Niantic last night (read more here about the bug) and can be used again. It’s too bad that it wasn’t available last weekend for those who were eager to play, but the game is still fairly fast.
Zorua can still be found in Pokemon GO. However, you can catch it with Pokemon GO Plus.
