This no longer seems to work

[LiamWinterton]

Currently following this guide: https://www.sanity.io/guides/nextjs-app-router-live-preview

Everything worked about from the actual visual editing.

I downloaded the example app router project in this repo and this also did not work.

Not sure what else to do here?

The app router guide and example code have been updated. Thanks!
