We have a site collection that has previously had sharing enabled and the reason I presume we now have an "Anonymous Users" group in our advanced SharePoint permissions.
Can anyone tell me how I can delete this group from the Site Collection?
I have tried using PnP Powershell but it doesn't work and I am unable to remove the group via the GUI.
It's a bit of an issue that this group can't be removed as it gives Security related concerns to people who see the group on their site permissions.
Hope someone can assist.
