I had the same problem. This is the solution I found: change your code in this way.
I realized this is already answered, but I found this to be the correct answer. It follows what FB has here. The image and/or link actually shows up in the dialog.
Stream. Publish didn't make that change for me. Also, the dialog page says that the stream.
Publish is old.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
