Troubleshooting

Can I make the cookies persist across other domains, not just subdomains?

No, this feature only allows cookies to persist across subdomains, like from ‘blog.domain.com’ to ‘store.domain.com’. Cookies will not persist from one domain to another, such as from ‘domain.com’ to ‘website.com’.
