Useless time sink
First try: The lack of instructions led me to try winging it. Though it went through after a few hours, result was a complete wash. Second try w/ 3rd party tutorials: waited hours for completion, but the ap sent up error messages when trying to view the finished model. Crashes when trying any of the social media features.
3rd try: trying a different app.
