In Confluence Cloud, I am having a problem where I can't tag users (@mention) on a page when I am using the legacy editor. (Specifically this is with the Page Properties macro, but it seems to be more widely spread than just that macro. I am continuing to test.)
I am able to tag (@mention) people/users in the new editing experience when I use the Page Properties macro there... The pages are in the same space as each other so I don't think it's a matter of rebuilding the index. Any suggestions of things I can try to troubleshoot?
