My user is seem in the assignee list only in certain projects

[Itay Keller]

When opening the Assignee drop down in our Jira cloud, my user can be found in some projects, but not in others.

How is that possible?

Hi @Itay Keller,

there is a permission "Assignable User" in the permission schemes. By this permission is decided if a user can be assigned to an issue or not.

So you probably have this permission in some projects and do not have the permission in other projects.

TLDR:

I added "jira-software-users" to my groups and it solved the problem.

LR:

I was looking at our 2 relevant projects, Moon & Mars.

The Mars project (where my name is seen) has these permission for Assignable user: 
Group (jira-software-users)
Project Role (atlassian-addons-project-access)

The Moon project (where my name is NOT seen) has these permission for Assignable user: Group (jira-software-users)
Project Role (atlassian-addons-project-access)

My user belonged to the following groups:

site-admins

jira-administrators

I added "jira-software-users" and it solved the problem.
