Steps
Check third-party cookies
Some SSO flows need third-party cookies. Add the SSO domain to Settings → Privacy → Cookie exceptions.
Clear the site's cookies
Click the lock → Site settings → Clear cookies, then try again.
Try Incognito
If sign-in works in Incognito, an extension or a cached state is the issue.
Try without autofill
Type the password manually. Some sites reject autofilled values incorrectly.
