on iOS 14.6, From a hybrid Cordova app, OIDC authentication URL is opened in SFSafariViewController, up on successfull login session cookie is set by the server. Applicaiton is dismissing SFSVC view and authentication is code is passed to hybrid app for validation. Next time (within few minutes or less that a minute) when SFSafariViewController is opened with OIDC URL, previously set session cookie is missing (This is needed for a switch customer case within App)
Sometimes it passes cookie, sometimes it does not. There are cases it never an issue on specif phone. but random behaviour on other phones with same OS build and make.
https://support.apple.com/en-in/HT212528 As per this URL, there are security fixes done on WebKit safari engine. Not sure some fixes causing this issue, but it seems intermittent.
Anyone facing cookie related issue on iOS 14.6?
