Ellessay review for Magic Zoom Plus

I want to use this app to do a function of enlarged pictures, But after I gave it partner rights, it changed the code of our store template, and on the new magnifying glass, it is also the product picture to join their own App Product Name and Advertising Jump Link. And after I delete this application, the code has not disappeared, and their advertisements are still hanging on the website product picture. I can only recreate a new template and decorate.
