Describe the Bug

Hey there 👋

I recently implemented live preview as described at

When I use Live Preview on a page it doesn't initially update the site until I manually enable draft mode (e.g. by clicking the "Preview" button). This is a confusing user experience as the page doesn't update even when it should.

Current Behavior

So you're right that there's a few ways to do this however Payload can't really enable LivePreview for you on it's own, you enable it via a Next API route.

In our website template see: https://github.com/payloadcms/payload/blob/beta/templates/website/src/payload/utilities/generatePreviewPath.ts

In your own code see: https://github.com/remarcable/payload-3.0-demo/blob/livepreview-repro/payload.config.ts#L47

In this line, preview is enabled and we're pointing the URL for it to the next preview endpoint which then enables draft mode in nextjs. So you simply need to do the same for livePreview

@paulpopus Thanks for your response, makes total sense. This was the exact solution I would have thought about, just didn't connect the dots.

Awesome!
