We can help with issues related to YueLiuli downloads and installation, learning content, pronunciation practice, AI Cantonese conversation practice, translation features, membership status, app crashes, display problems, and feature feedback.
For issues caused by Apple ID, App Store payment processing, system permission restrictions, device system problems, or third-party platform policies, you may also need to contact Apple or the relevant platform.
iOS users should download and update YueLiuli through the App Store. If download fails, please check your network connection, Apple ID status, system version, and available device storage.
Android users who use the official APK should make sure the download comes from this website domain. Before installation, check whether your system allows installation from the browser or file manager. Please do not install unofficial packages from unknown sources.
YueLiuli memberships are managed through Apple App Store In-App Purchase. You can view, manage, or cancel subscriptions in your Apple ID subscription settings.
If you subscribed but membership access does not appear, check your Apple ID, order status, and network connection, then restart the app or try again later. Refund requests usually need to be submitted through Apple's official refund process. The developer cannot directly refund App Store orders.
Speaking practice, AI Cantonese conversation practice, pronunciation correction, and speech recognition features may require microphone permission, speech recognition permission, and a stable network connection. You can enable or disable these permissions in system settings.
AI-generated pronunciation feedback, expression suggestions, conversation replies, and practice scores are for learning reference only and are not professional language proficiency certification. If recognition, feedback, or replies seem inaccurate or unsuitable for a context, please use your own judgment and send feedback to us.
To help us diagnose issues faster, please include your device model, system version, app version, time of the issue, affected screen, steps to reproduce, screenshots or screen recordings, and whether you have tried restarting the app or reconnecting to the network.
