My progress isn't saving

1. 01Confirm you're signed in — progress and saves need an account.
2. 02Check you're on the account you normally use.
3. 03Private/incognito windows and strict privacy settings can clear the session between visits.
4. 04Sign out, sign back in, and re-open the page.

If progress vanishes on a normal signed-in session, tell us which course or tool and roughly when.
