This usually happens when the subscription email doesn't match your Underleaf account email. To resolve this:

1. Check which email you used during subscription (check your receipt)

2. Make sure you're logged into app.underleaf.ai with the same email

3. If they don't match, contact us at team@underleaf.ai with both email addresses
