Tweet counter always at 0

Hello,

I noted any problems with the tweet counter, it remain always on value 0. I read who it depends from the Twitter system update…but also after many hours, the counter is always on zero, also when the post is have been shared more times on Twitter. It’s really strange.

I am using the default settings, with “Interval to update stats”, at 1800 seconds.

I have the same problem, on all posts and pages.

Thank you,
Regards!
