Duplicating Notion pages from published Notion site failing

This incident has been resolved.

We're investigating an issue where duplicating a Notion Sites page "as a template" can fail and show a "This page couldn't be found" error. Our engineers are working to ship a fix and will share another update once it's deployed. If you hit this issue, try changing the URL host from "app.notion.com" to "notion.so" and then duplicate again.
