This app is F-ing stupid bro I changed my number and all of a sudden I'm not allowed to make any purchases! You guys need to make it easier to send codes through email and not by number so often! I can't believe this app costed me a limited released that sold out as I changed my number. It doesn't need to be so complex to change your number for this damn app. Simply make it easier instead of logging in on the web to do so!
