Why don't my edits show on my live site?

Most likely they're saved as a draft and haven't been published yet. Open Site: if it says Unpublished changes, tap Publish changes and they go live.

On a free preview nothing is on the web yet; tap Make it live first. If Publish changes is greyed out, there's nothing new to publish. If it says publishing is paused until your payment goes through, update your card in Billing, then try again.

Still seeing the old version after publishing? Your browser may be showing a saved copy; refresh the page or open it in a private window.
