Thanks for adding me as a admin of the app. I just logged in using Facebook, read an article, and it was posted to my Activity Log in Facebook. The action is working now. Try testing yourself and then going to the URL below to see if the activity was added:
www.facebook.com/me/allactivity
If that seems to be working for you, you can follow the steps in our
Testing your Actions
and
Submitting your Actions
documentation. There have only been some minor changes to Facebook in those areas.
I hope that helps,
Alex
