Using Jira Cloud.
I have 2 projects. Both use the default permissions scheme but in one the Assignee dropdown includes all staff and in the other the only assignee option is to assign to me. Anyone can assign to themselves, but no one can assign to others.
Assign Issue permission and Assignable User permission both include "Application access - Any logged in user"
Permission helper says each user has the Assignable User permission.
I've tried adding everyone in the developers role (didn't work)
The only difference between the projects is that the non-working project uses custom workflows which assigns the correct default users as part of the transition as a post function.
Any ideas why?
