Up until a week ago, all of the columns on our Kanban board had a "Create Issue" button below the last card in each column. That button is now missing from each column. What's more perplexing about this is that it disappeared while I was on vacation and I'm the only one who really uses it, so there were no workflow or status changes made.
I ruled out this being a caching issue since the behavior is repeated in both other browsers and private mode.
This button was great because it allowed me to add issues to columns without having to create them using the primary button, then go to the backlog, then move them to the board. This is a team-managed project.
Does anyone have any ideas what may have changed or what to check?
