UTK.io developers, please add your texture pack creator app to all Amazon devices, and the Amazon app store. You should start working on it after Blocklauncher updates to support 0.13.0 (Which may be anywhere from a few hours to weeks). I know you most likely are able to do this, because you have your custom skin creator app on the Amazon appstore. I will check Gmail and the Amazon appstore every once in a while to see if you have done my request.
