I have a website that is developed in React, in which we have implemented logging in to a third party via an iFrame. This works as expected in all browsers we have to support, except for WKWebview on iOS, which refuses to set cookies on another domain in the iFrame. We have a React Native app that shows the webpage in this webview, so we kinda have to support it.. From a lot of googling around I've found various workarounds that no longer work, and ended up at Webkits bug page: https://bugs.webkit.org/show_bug.cgi?id=204109 and this from SalesForce: https://help.salesforce.com/articleView?id=000351155&language=en_US&type=1&mode=1 It is unclear though whether or not this is actually fixed or if it has been reintroduced (seems like it has, as it's not working on iOS 13.3 devices). Has anyone had similar experiences, and even better, a potential workaround?
Thanks in advance
