My FB app sends links to users through the Send API inside a generic template. Most of the time, these links work fine, and Facebook opens the in-app browser and takes you directly to the web page. However, some links bring up the page below. Why is this happening for only some of the links? This link is about a month old. I've found it fairly difficult to get in touch with Facebook developer support, so thought I could get some help here.
Here is the image of the Facebook warning: "Leaving Facebook" warning
Thanks in advance.
