Developers are never wrong. You contact them with problems and when they do respond, they either ask for impossible proof like in game images of the problem (as if your supposed to anticipate one) or they give you a solution that is completely ridiculous, like changing the time on your phone, then resetting it and your phone when your rank bar stops progressing. It's funny how I can't get a solution regarding my specific issue though, and it took reviewing publicly for a quick response.
