This issue needs to be tested in a device with iOS 14+ and another device (either iOS 13- or Android). Setup In web as teacher, create a page and put an iframe pointing to the same site. There's one already created in MM Testing > Resource: Page > Page with site internal content embedded (via iframe). iOS 14+ Login in that site and open the page. In the iframe, check that you need to login. Try to login in the iframe. Check that you're asked to login again, you're in an endless loop. Check that below the iframe you see the text "Is this content not working?". Click that link. Check that you see a modal explaining that you need to enable a setting. Click "Open settings" and enable the Cross-Site setting. Wait 6 minutes to be able to auto-login again. Otherwise you can just go ahead with the testing but you'll need to authenticate manually in the iframe. Open the app again (the app is killed after changing the setting). Go to the page. Check that the iframe now works fine. Go to More > App settings > General. Check that you see an entry about cross-website tracking. Check that clicking the button also opens the app native settings. iOS 13- or Android Make sure 6 minutes have passed since the iOS 14 test, or user another user. Login in that site and open the page. Check that the iframe works fine. Check that you do NOT see the "Is this content not working?" text. Go to More > App settings > General. Check that you do NOT see an entry about cross-website tracking.
