Hi There,
We have a web application with URL "testA.com"that uses IFrame and src into a different domain URL"testB.com" Page B. The Page B Content-Security-Policy uses frame-ancestors to allow Page A to IFrame into Page B. Also Page B is not using Cookies.
This setup works on other devices and its browsers like Android, Windows with Chrome, Firefox Edge but does not work on IOS 13 + on any browsers. The only way to have this works on IOS is to switch off the Prevent Cross-Site Tracking option.
We found that this stops working coinciding to the WebKit updates https://webkit.org/blog/10218/full-third-party-cookie-blocking-and-more/
Just wondering is there anything else that we missed to get this working on IOS?
thanks,
