For some of our users, we get often get draw.io diagrams not rendering onto the Confluence page.
Typically we get a progress wheel spinning, but never a rendered diagram.
So far this is happening to users with Google Chrome browsers.
This has happened after a creator of a draw.io diagram saves the diagram and returns to the Confluence page.
As there are many possible root causes, what can we do to troubleshoot? What have other users done when the draw.io diagram does not render onto a page?
