If you are using the CleanUp feature because you've seen your excessive links on your Manage Inventory page, select Facebook Cleanup under inventory.  Sometimes, after entering the group name, you will get a message that says "No albums".  You know there are dead links to albums in this group, because you can see them on your Manage Inventory page!  A few things you can do: 

        - Make sure there are no emoji's in the group name.  That can throw off the system

        -Logout of POP, and back in.  Sometimes functions get a little stuck.

        -Try cleaning a different group, then come back to the first.  We've found the connection has a harder time with some groups, but will grab onto it once you've completed the CleanUp process on another group.
