Created attachment 109853 [details] Screenshot In the Application Addons results list, there are many applications that don't have an icon to represent them. Instead Discover shows a white square. My suggestion is to use a generic breeze icon that represents applications to replace those images missing.
At the moment we are getting such a thing: https://cn.pling.com/cache/100x100/img/default.png Will see how to fix it in the store...
