Hello, Thanks for your response. The upgrade to iOS 14.5 fixed the issue only for some users. Not for all of them. I specified the user-agent just to show you that the user who still experience this issue has upgraded to iOS 14.5. Here are the details regarding the circumstances in which the problem occurs: An in-app browser tab is opened (ASWebAuthenticationSession) to let the user login to our application (OIDC flow) The user authenticates and the authentication server redirects him/her (with a 302) to the authorization endpoint with a set-cookie header containing the session cookies (set-cookie: session=xxxxxxxxxx; path=/; expires=Thu, 20 June 2021 20:25:45 GMT; samesite=none; secure; httponly) When calling the authorization endpoint, after redirection, the cookie is not sent to the authentication server by Safari. The cookie header is empty. What is strange is that this only affects some iOS users on different versions including 14.5 ... Regards,
