Hi Atlassian Community,
I've encountered an issue where team members with the standard member role are unable to mention a person via suggestion after typing @firstname or @lastname in the description field when creating a task or bug. They get suggestions when assigning tasks but not in the description field, even though the person they want to mention already exists in Jira. Screenshot attached (@chri "Teammitglied zu Jira hinzufügen").

Here is a screenshot from my perspective (admin role). I haven't changed any roles, and after checking them, I couldn't find a specific setting that enables this feature. When I type @firstname or @lastname, I do receive suggestions for people to tag.

We use this tagging method in the task or bug description to request further specifications or similar input from team members.
I would highly appreciate any advice on how to resolve this issue.
Best regards from Austria,
Christian
