Symptoms
- Credentials rejected
- OTP never arrives
- Spinner forever after tapping login
Likely causes
- Typo in mobile number or password
- Outdated client
- SMS delay from the carrier
- Unstable connection mid-auth
Fix steps
- Confirm country code and number format.
- Use forgot password / OTP reset if available.
- Update to the latest APK.
- Retry on the other network type (Wi-Fi vs data).
- Check the full login guide for registration binding tips.
Prevention
- Bind email/mobile early
- Store password in a secure manager
- Keep the official APK updated
Most login failures are credentials, OTP timing, or an old APK. Work those three before assuming the account is gone.
