| You see | It means | Do this |
|---|---|---|
| Code screen, nothing arrives | Slow delivery, filtered texts or a typo | Wait, check spam, resend once |
| "Too many attempts" | Codes are paused for that number | Wait a few hours |
| "Number not supported" or "invalid" | Wrong format, or a number type the app refuses | Re-check format or use a mobile number |
| "Number already in use" | Another account has it | Sign in to that account or use another number |
| "Code incorrect" or "expired" | An older or late code | Request one new code and enter it at once |
