Hey Gus,
Thanks so much for reaching out to us about this and so glad to hear you were able to get the buttons functioning correctly on your site.
With regards to shares, that’s a bit odd if you aren’t seeing ANY share counts return (especially from a network like Pinterest) but as far as Facebook goes we’ve seen some changes occurring with Facebook’s Graph API on their side of things.
As far as we can tell, Grow Social is doing everything correctly with requesting the share counts from Facebook but Facebook is still returning a 0 count for some posts. Since that is the count sent back from Facebook, that’s the count Grow Social will use.
We have seen a few issues already opened with Facebook’s developers and it appears they’re taking a look at those changes so hopefully fixes to that come soon!
As far as Pinterest goes, would you be able to send us an example URL of a post on your site that has been shared to Pinterest but isn’t returning any counts?
