I use Confluence cloud and sometimes using @mentions in pages, my colleagues` ID name is not recognized and appear as "unknown users" in tag.
When I go to edit the page, their names appears as normal.
Yet my problem as admin is when this page has this error they won`t get notification via mail of any modifications within that page by other colleagues.
Do you have any answers what is the issue in here? Or what should I do next? What should I expect to happen? Or do you have any tips&tricks to solve this?
Thank you.
