the last update brought lots of serious bugs! The rare chrono crystals (game currency) that have been earned or bought by real cash did not add to the inventory but they are always deducted when you use them!!! The Contact Us function only brought you to a short FAQ so there is no way to report the error. I advise against paying any real money ATM unless they fix the problems and if you encounter the same problems contact google pay or apple store for refund.
