Hi @PeterAtthem
To answer your question, it is not possible to render React components in the export view, instead, your app will provide export content in Atlassian Document Format (ADF).
The tutorial linked above is the correct tutorial for using the adfExport feature. This is the most up to date tutorial for exporting macro content.
@AaronCollier You mentioned it was outdated - are there any particular issues you found with it, asides from what’s in the other thread you linked, that we’ve already raised bugs for?
