Hi KimZener1357366
As the KanBan app is a ranking tool as well as a workflow tool the position the cards hold in the column indicates their ranking.
The Rank field itself is not available for display on the cards for this very reason. If, however, you are using a Manually Ranked workspace then the drag and drop ranking of cards is no longer supported and the rank value us still not available for display.
We do not suggest using manual ranking if you want to follow KanBan methodologies.
Please let me know if that helps.
