Allow iframe embedding of Prezi presentations
This line in the iframe prevents it
sandbox="allow-forms allow-scripts allow-popups allow-same-origin allow-pointer-lock"
Unfortunatly that means prezi is also blocked and error messages like this occur
Access to Script at 'https://www.googleadservices.com/pagead/conversion.js'; from origin 'https://prezi.com'; has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://prezi.com'; is therefore not allowed access.
If you could add a check box which removes the sandboxing on iframes that would be great
Many thanks for the wonderful product
