Mermaid diagrams not working for me, but work for my colleague

My colleague sees diagrams… I get the following. I’ve attached a screenshot and included logs that appear to be coming from the JS within the iframe. My colleague is an admin and I am not, could that be the issue, when I view the page he setup, I get the same issue, I can see the code blocks, but the diagrams produce the error message below.

Would be amazing to get mermaid diagrams in our confluence space!

More investigation today, broadly everyone in our instance can see the diagrams, except me…

I also noted the following resposne when it attempts to load the page content from the api..
“The app is not installed on this instance”
