The linkCaption field is blank in the Facebook Unity SDK FB.Feed

I am using the Facebook SDK for the Unity, and I’m building to android. When I attempt to run FB.Feed() and pass strings for the method’s variables, the feed dialog appears and everything seems fine. When, however, I check Facebook for my post, I notice the linkCaption is not visible. The visibility of linkCaption seems to depend on what link I use for the link parameter: if I use www.google.com the caption shows up perfectly, but if I use my app’s facebook page, Facebook it doesn’t show up at all. I have no idea what’s going on…any ideas?

Also, does anyone know how to make the share dialog that can be used with Android or iOS natively work with the Unity SDK? I would prefer using that to the Feed method, but I’ll be alright using that if only I can get that caption to show up. I’m not certain if this is the best forum to post this, but I can’t find a forum for Facebook developers.

linkCaption = Ignored if sharing a Google Play or iTunes App Store link.
linkDescription = Ignored if sharing a Google Play or iTunes App Store link.

This means that your message will not be shown if your sharing a Google Play or iTunes App link and
that probably the same with Facebook links.
