Hi Mel,
"...Facebook will automatically upgrade the call to a newer version when that is deprecated..." = Are you sure ?
I'm asking because as you can see, "automatically" (no action from my part), I found my two FB Api fields settings as "blank" and if I open the dropdown menu I just have the v13 / v14 option to select... I add an image for you
I suppose it is blank because FB automatically update my API to a newer version.
Here a useful link of the APIs Changelogs:
developers.facebook.com/docs/graph-api/changelog?locale=en_US
Waiting news from you, thanks for help on understanding...
