When using a Trello board macro in a page that will also contain a roadmap macro, the Trello board will be displayed as a blank session after publishing the page.
- Create a new page in Confluence
- Add a Trello Board with an URL from an existing board (in the edit mode, click on Insert > Other Macros > Trello Board
- Add a roadmap macro or Jira issues Calendar macro on the same page
- Publish the page
The Trello board should be rendered properly.
No workaround at the moment would be removing the roadmap macro so that the trello board is rendered on the page again.
