I have a project for which I'm an administrator, and just in the last week, I can no longer release issues from the "Done" column of my Kanban board. I was last able to release issues on 12/12/2018, but I recently noticed the "Release" button no longer appears on my board.
I have a colleague who can see the release button, but the button is disabled for him, as he is not a board or project administrator.
I am a board, project, and Jira administrator and have not updated my permissions since this problem started.
How can I get the release button to show up on my board again?
