I've created a custom card in Custom kanban board and now I'm unable to delete the card. I have role of "Manage cards" in the board. Attached is the screenshot.,Kindly assist.
Each role in Jira Align is currently customized when the instance is set up.
I recommend to check with your Jira Align Admin to see if you role is supposed to have Delete capability for the Kanban Boards.
As you can see in the image below, the custom Kanban permissions are very granular and can be altered by role.
Interesting. This article, 10X: Add Cards to a Kanban Board, might be of use.
This issue could also be caused by a permission setting within your role under the Additional Options section.
You will definitely need Admin rights to troubleshoot at that level.
PS: I did warn you to avoid custom Kanban functionality. :-)
