Atlassian has made a security change to the Confluence Content Body Conversion API. When this API is called by an app, any macros in the content, which are provided by another app, will not include that app’s context JWT. This means the macro may not be rendered by calling that app’s endpoint.
We do not expect apps to be rendering macro content from other apps so we do not expect this will impact most apps. If your app is impacted, please contact us to let us know why your app needs to perform this operation.
