When users navigate to their Classic Boards, they see the Atlassian notice regarding deprecation of Classic Boards in March 2015. This is causing confusion and creation of internal support tickets as our users think that we are the ones deprecating Classic Boards.
Atlassian was unable to give us a solution, so I'm posing to the community - Have you been able to safely and consistently modify/disable the Atlassian-created footer that appears in the Classic Boards?
