when you use the mermaid app to display mermaid diagrams from a code block on a page you can see the graph on the page, however when you then include that page in another page the graph doesn’t show and instead shows the text “Mermaid Diagram”
Ugh, IDK if this is something I can solve as an app developer, this seems more like a general apps platform issue. Could you try it with other apps for confirm?
This app is now open-sourced and released on github - GitHub - atlassian-labs/mermaid-diagrams-viewer: A Forge app (for Confluence cloud) that renders mermaid diagrams from code blocks in Confluence pages.
Please feel free to raise issues or contribute there. Side note - to reduce support burden, I will not be monitoring topics about this app here.
