Troubleshooting steps
- If an embedded form spins or returns to the start, open the provider’s official sign-in page in a separate tab in the same Safari window. Use the address published by the provider.
- If only the standalone page works, record the two domains and reproduction steps. Safari tracking prevention restricts third-party cookies, so the site operator can check how its embedded flow handles those restrictions.
How to choose the next step
If both fail, note whether the error occurs during page load, credential submission or second-factor verification, then troubleshoot that stage.
