since I have installed the Update to version 3.7, no sites and devices can see the “opt-out” Iframe. Google says the host reject the connection. But if I open the Link directly in my Browsers, I can see the content. Just not in the Iframe. I generated a new Iframe in the Matomo Panel but also it wasn’t shown
Can you open the website where the iFrame is embedded in your browser and open the browsers developer tools? It should show you the error.
You can also send the URL of that page to me via a direct message if you want to.
I found the error. The Admin has changed some security Options and added the X-Frame option.
