Try to find a saved draft
As long as you're connected to the internet, the Tettra editor will autosave all your drafts. To check if there's a saved draft, click on your name in the top right and click the "drafts" link.
Please reach out to us directly if you're unable to find your missing draft or page. In most cases, we're unable to recover a draft if it hasn't been saved to your Drafts section, but we'd be happy to help troubleshoot before confirming one way or another.
