Hi there,
I am currently trying to solve an issue with columns in next gen projects. I already searched though older posts but they delivered no solution.
I am not able to add or rename or delete columns on a next gen project. However, I am able to do all this in a classic project.
So I don't consider the cause of the issue in administration problems. I am the only user in my organisation tho, so I am administrator, project owner, board owner, etc.
Currently I am using the free version of Jira Software.
No board settings / or the "+" symbol to add a new column in Jira next gen project:

Board settings available and the "+" button to add new columns in Jira classic project:

Any ideas or solutions to solve this issue?
Thanks in advance
Katja
