Hello @Suzannah_Ibrahim ,

The permission to use mentions relies upon four items:

• Permission to the 'Browse Users' permission
• Wiki Style Rendering for the affected field
• Email visibility of users
• The mentioned user does not have Browse Project permission

The main cause is a user not belonging to a group currently granted with 'Browse Users' permission.
