How do I undo a change or go back to an older version of my site?

In the editor, tap Undo (or press Command Z, Ctrl Z on Windows) to step back one change at a time, and Redo to step forward again. Every change is saved as its own version, so nothing is lost.

On a live site, the Site page lists every version you've published under Published versions. Tap Restore on one and it becomes your draft; look it over with Preview changes, then press Publish changes when you're happy. Nothing changes on your live site until you publish.

To throw away all your unpublished edits at once, tap Discard changes on the Site page; your draft goes back to what's live.
