The 3 States of a Social Card Icon

  If Social Card is only Grey (without a Red Dot), it indicates that the original Long URL associated with the Short Link has proper OG (open graph) info of Title, Description & Image and you may use it as it is for posting / sharing

  If Social Card is Grey with a Red Dot, it indicates that one or more OG (open graph) data is missing or wrong in the original Long URL associated with the Short Link. You can then Edit the respective OG Title, Description, or Image as you need to make it proper for sharing / posting.

  If Social Card is Green, it indicates that you have made changes to the OG and it is proper for sharing or posting on social media
