The SharePoint Move/Copy dialog was recently updated to have two sections: Recent and Teams. The "Teams" section does not include SharePoint sites that are in O365 Groups without Teams.
This is limiting. Recent does not show all recent sites. Teams excludes Group only sites.
In short, we need our users to be able to get to the entire list of SharePoint sites they have access to from the copy/move dialog so they can copy/move files between any two SharePoint sites whether it is a Group-only, Teams site, recent or non-recent site.
