Hi,
So I created basemaps for our organization, added both the tile layer and the webmap to the group which I nominated as gallery for our basemaps. Both items are shared to organization and group is shared to organization as well. I mirrored the setting from our 10.8.1 portal (no issue) but still giving this warning/error: You don't have permission to update sharing of this item. This item may not be visible to others because it's shared differently.

Is someone having same issue with us? I am with ESRI support as well but still no resolution and they are unable to replicate from their end
