# SWAPP - Third party cookies must be allowed

**Description:** When the SWAPP launches, a popup appears with a message saying `ERROR: Third party cookies must be allowed for domain "https://spotfire.your-company.com"`.

Starting in February 2020, Chrome 80 introduced the SameSite policy for cookies (read more [here](https://developers.google.com/search/blog/2020/01/get-ready-for-new-samesitenone-secure)). This new policy aims at securing cookies cross-domain and blocks third-party cookies.

Spotfire has implemented this feature which can cause mashup application to stop working, as [described on their support site](https://support.tibco.com/s/article/Tibco-Spotfire-JavaScript-Mashup-API-stops-working-in-Chrome-due-to-SameSite-problem).

To fix this issue, you need to change the SameSite attribute on the server and set it to "None". See [Spotfire Documentation](https://docs.tibco.com/pub/spotfire_server/latest/doc/html/TIB_sfire_server_tsas_admin_help/server/topics/samesite_cookie_attribute.html) for more details.
