I have a Giovanni mission I CAN'T do because for some reason Niantic picks and chooses when to take him out of the game. So now I have to wait weeks possibly months before I can fully complete the special task. It's frustrating to say the least. As a returning player this only discourages me from wanting to play, this baffling feature/mechanic deserves 0 stars if I I could give this game that rating. Pretty disappointing.
