Work through these in order — the first two fix nearly everything.
1. Check which account you are signed in to
Progress belongs to the email address you signed up with. Signing in with a second address — a work one instead of a personal one, or an address with a typo — produces an empty account that looks exactly like lost progress. Open your profile and check the address before anything else.
2. Reload properly
A stale copy of the app can sit in the browser cache after an update. Reload with a hard refresh: Ctrl+Shift+R on Windows, Cmd+Shift+R on a Mac. On a phone, close the tab or the installed app fully and reopen it.
3. Try another browser or a private window
Ad blockers and privacy extensions occasionally block the app's own requests. A private window loads without extensions, which tells you quickly whether that is the cause.
4. Check your connection
The app stores a local copy of your progress so screens draw instantly, then reconciles with the server. Offline, you may see a screen that looks out of date; it corrects itself when the connection returns.
Still wrong
Write to support@betterskillai.app with your account email, the device and browser, and what you see instead of what you expected. The server holds the real record of your progress, so a genuinely missing completion can be checked and restored.
