Now, I did notice when it was working for me, that if I entered the fillup data on the website, it posted to Facebook. If I posted the fillup from my cellphone using the mobile site, it never posted to Facebook.
Same issue - nothing will auto-post to Facebook. I reset and reauthorized and also checked my Facebook app permissions. All looks okay. I DID notice that when the first Facebook authorization pop up appears, it says "This does not let the app post to Facebook." BUT later on in my app permissions, it shows it can.
