Several people have been having problems with the share button not working. If your going to have this complex plugin, then you should have more dedicated support, like an actual WEBSITE with a ticket system.
Businesses are using this plugin and to make them wait several days to fix or to even offer help is ridiculous. Do what other plugin creators do, charge for premium support.
Anyway, same problem as others, the share link isn't working. I have ALL other plugins deactivated, so not sure but we obviously would like for it work correctly.
