Third-party cookie deprecation and its effect on SeamlessAccess Is your SeamlessAccess button acting weird? Not showing your remembered institute as you expect? This might be due to a new browser configuration setting that blocks third-party cookies. Without those cookies, the SeamlessAccess button (i.e. “Access through..”) will work differently than you might expect - but the other SeamlessAccess services (login, discovery, remembered choice on the discovery page) continue to work as before.
