I Figured it out.... sorry to bother everyone!
Am I correct that there are TWO calendar views for Trello now?
I want to see checklist items but my "normal" Calendar button no longer shows up. This article says I need this "normal" Calendar view to get checklists. https://support.atlassian.com/trello/docs/calendar-view/
All I see the Workspace Calendar but this article says it does not populate with checklists. https://support.atlassian.com/trello/docs/workspace-calendar-view/
I have the Premium Version - Your help is appreciated. Katie
