Thank you so much! I like your project and the final video! :D you made a good work. It doesn’t look like the work of a beginner!
My prototype link that’s in the post works fine https://invis.io/XR84MXBTA
That’s weird.. Try to access it from computer when you can. On iphone there’s the app of Invision but I’m not sure that they have released the android version of it.
