I have an issue where myself (site collection administrator), and the site owners cannot see Access requests and invitations under the Users and Permissions section in Site Settings on a couple of sites. It shows up there on some other sites for myself and the site owners of those sites. As far as I can tell they are all team sites.
I know that you can get to it using the Site permissions link.
My question is what causes it to show up there? I looked through my Site Features and they are the same for the sites that have it show up as the ones that don't.
