Why do I see “This rendering mode is not supported.“?
The HTML Macro application is designed to generate dynamic macros for inserting I-frames into the Confluence pages by default. However, it has limitations, especially when using Confluence's Native PDF export feature. Confluence does not support the export and rendering of dynamic macros in this scenario.
The only possible option in such cases is to use the static macros. Using static macros ensures compatibility with Confluence’s Native PDF export, addressing errors or limitations linked to dynamic macros.
