I've recently upgraded our Confluence DC test environment from 8.5.23 to 9.2.5. After upgrading, I noticed a bug where we're unable to add new people to Page Restrictions. I can set a new restriction on a page, which will put me on the list of people who can view and edit. However, when I try to add a new person, then click apply, and then come back and view the list of people with view/edit access, that person is not on the list.
I have engaged Atlassian support and we checked some things out including the network logs (which seems fine, all 200s) and checked the DB to ensure the restrictions are not showing up in there, but while they are reviewing the latest data I figured I would reach out to the community to see if anyone else has encountered this problem.
Thank you!
