    you must ALSO turn off any tracking or blocking software, such as Norton Tracking, since that will case the error even after 3rd party cookies are allowed

    We had a customer see this Invalid Authenticity Token error after-sign in (but only for Zendesk sites that used our domain, and only with Chrome) - the DuckDuckGo Privacy Essentials plugin appears to be responsible.

    Logging in with other browsers worked, and logging in with incognito worked fine.

    We ended up disabling the privacy plugin but it would be of great benefit if we could use our own domain and allow customers to sign in with this plugin enabled, since we cannot control what plugins our customers use and do want them to be able to sign in.
