Aviary web SDK crop tool and mobile browser features not working

I am developing a web site which uses the aviary SDK web. What I has found is the crop feature cannot use to rectangular crop of image. For mobile applications I cannot use meme feature. Keyboard is not displaying and other features also not properly use. you can see the tool added at http://ift.tt/2dHJqQk. select dimension from dropdown and click next. Then next tab appears and you can upload photo using facebook, instagram , computer or dropbox. Please check and give me a solution.
