Google Chrome recently announced changes to how the browser will treat cookies in February of 2020.
FullStory's recording functionality will not be affected by this change.
The cookie FullStory uses for recording, fs_uid, is a first party cookie. We place SameSite=Strict on this cookie which protects it from external access. So, for your end users, everything will continue as normal and recording will take place as expected.
Separately, there's an issue where FullStory customers are seeing cookie errors for our third party cookies. These only show up for users of FullStory when they visit a site FullStory is recording on. We are aware of the issue there and are exploring ways to mitigate those messages. It's important to note that the messages are purely warnings and won't impact your end users or recording/playback. They're safe to ignore for now and won't effect your ability to use FullStory.
