They have finally arrived! The ability to see the site collections created with private channels in Teams! THANK YOU MICROSOFT!!!! Intranet Admins everywhere can start breathing a sigh of relief! Site sprawl and hidden content from Teams is causing headaches across the globe. This will help greatly in seeing what’s going on from the SharePoint Admin Centre in Office 365.
You can’t do anything with them. You’d need to give yourself access from the Teams Admin Centre, but least we can see them here now too.
