The app is very good, unfortunately it doesn't work with the chrome browser. Error:
The app could not be loaded This app cannot be loaded due to a problem with the browser cookies. Try to activate cookies in your browser, try another browser or contact the developer for help.


I downloaded the app because I was trying to add affiliate link/banners to my shopify store and couldn't find a way to do it until I found the Youtube video about this app. I downloaded it and I started having trouble with adding the code. Andrew was extremely helpful and I couldn't be more happy with this app. It was exactly what I was looking for.
