Application running at domain https://lo93p.csb.app/
In Chrome browser on Android, when opening https://lo93p.csb.app/Test.pdf in iframe, it raises error:
SecurityError: Blocked a frame with origin "https://lo93p.csb.app/" from accessing a cross-origin frame
Same application is working perfectly in Chrome browser on windows desktop.
You can access this app as it is publicly available on CodeSanbox platform at https://lo93p.csb.app/
Target is React app with printing PDF silently on client-side.
Tried both dynamic iframe based on this Print PDF directly from JavaScript and library printJS (https://printjs.crabbly.com/)
Problem occurs not only on CodeSandbox but also on actual app hosting environment when accessing app in Chrome browser on Android.
