Quick fixes and one clear next step
If you can’t sign in, try these steps before contacting support. Start by updating the app and confirming the login details you entered at Ninewin. Then follow the checklist below.
- Update the app to the latest version; outdated builds often fail compatibility checks.
- Clear the app cache (Settings → Apps) and retry; cache corruption can block authentication.
- Use “Forgot password” to reset if two‑factor prompts fail; store credentials in a password manager.
- Switch networks (mobile data vs. Wi‑Fi) to rule out local blocks or DNS issues.
- Log out of other devices and enable 2FA for ongoing security.
Takeaway: if update + cache clear don’t help, reset your password and enable 2FA before opening a support ticket — those steps fix the majority of login problems and protect your account.
