Prismic preview links for unpublished documents cannot be previewed unless logged into prismic

On both of our repos, I’ve found that unpublished documents cannot be previewed unless the user is logged into Prismic.

I’ve shared preview links with people outside our department who do not have Prismic logins, but they consistently receive errors or are sent to blank pages. From my testing, this only seems to happen for documents that have never been published before.

Could someone please look into this?

Please see below - I’ve demonstrated accessing the same preview link both from a logged-in tab and from an incognito window.

Hi Sasha,

In your test third-party cookiers are blocked by default. The previews won't work in this case.
