I am owner of a lot of FB groups. I have biggest local selling group, most important one to PIN TO TOP posts. Now Im unable pin to top post. It says that there is already pinned post, but there is nothing when I try pin to top. It works normal. It tells me that there is already pinned post and if I would like to contnoue with new pinned post. I confirm that and its not working. Pin to top works perfect in different groups but not in this one. I have tried with plenty of accounts to pin post, I have tried to pin post random posts. Nothing works. Where I can contact support? Or can anyone help me?
