Troubleshooting Visual Editing with Sanity and cookie issues

I’m trying to implement Visual Editing following this guide: https://www.sanity.io/guides/nextjs-app-router-live-preview .My implementation differs in that my studio is hosted on sanity.studio url instead of being embedded in Next.
Does Visual Editing (Presentation) require the studio to be on the same domain?

One of the issues i see is that the

__prerender_bypass

cookie does not work as expected.• I open my sanity.studio and go to “presentation”
• I can see in the network request that the cookie is actually being set once the

/api/draft

request is triggered• Editing and preview works as expected.
• However, when i open a new tab and visit the website, the

__prerender_bypass

cookie is not set.I suspect this might be because in sanity.studio, the preview is loaded inside and iframe and that the browser restrict the cookie on other tabs/windows.

Any thoughts or suggestions?

👋 Visual editing doesn't require you to be on the same domain. Which browser are you using?

Brave.

I can see that the cookie response headers looks correct with SameSite=None and Secure.If i enable third party cookies in Brave, it works.

Right, but does it really require third party cookies to work?I mean, no browser will support this pretty soon… If this is by design, then i would suggest throwing up a big gotcha in the docs
