Facebook Autoposting & Revoke Access

Recently I had to revisit the Revoke Access piece of the Facebook Autoposting. After revoking access, then re-logging into Facebook, the token seemed to update again. But after creating a post yesterday, the autopost to Facebook did not work. I no longer see the drop down to select "Post as Facebook Page" like before.

This used to work, so now I'm wondering what I've done wrong. Here's hoping someone can help me understand the Revoke Access token and how that prevents the autoposting from working correctly.

Thank you
