At Grade.us, we've had a few different customers mention to our support team that the numbers of reviews and recommendations are not matching up with the actual numbers of recommendations on their Facebook business pages.
In all cases, the numbers have been higher, and customers are wondering "Where are all of these reviews and recommendations that I'm not seeing?"
