We are getting several users reporting issues loading the Page Properties Report on one of our spaces. I can't replicate this myself but other users (working for different external companies) get this error...
When you try to open any subpages in the "Use Cases" section , it gives an " Error loading the extension!" message. Reloading the page a few times resolves it but opening it again / navigating to other pages in the same section also results in the same issue.
