The Kaltura video tools included in LMSs - e.g. My Media, Media Gallery, Shared Repository and content embedded using the Kaltura icon – require support for session cookies.
In recent months several browsers (including IE and Safari) changed their default settings to block third party cookies.
If users are experiencing a message like “"it seems your browser is blocking 3rd party session cookies", please enable cookies in that browser.
Another option to resolve this issue in a more permanent way is using an alias for the KAF instance. See information on how to do that here.
For additional information see How to avoid the "3rd party cookie" error message in the KAF based LMS Integrations.
