Hi everyone,
I downloaded and started to use this component Power Apps iFrame Component - Power Platform Community (microsoft.com)(thank you April and Yash Agarwal!) to embed iFrame in my canvas app. It works fine, with some VS changes it resizes and works properly. The problem comes with the source, here are some attempts:
SharePoint as a source, it works fine:

A web ("https://www.gazzetta.it/")

Another web, this one doesn't work ("https://www.google.com/")

Last one, doesn't work either, it's an SAC, SAP Analytics Cloud link (cloud). All permissions are granted since I can see the content directly via browser:


As you can guess, my real goal is to embed the last one in the canvas app. Why does this happen? Why does it happen in a website like www.google.com? Is there a solution/workaround for this?
Thank you so much in advance.
Wesker
