The split mode functionality in Youyou NPV for China accommodates web applications such as Telegram, WhatsApp, or Gmail, which make use of HTTPS. This feature can modify the routing for both HTTP (port 80) and HTTPS (port 443), allowing access to the web versions of these applications. Nevertheless, the application versions may operate on different ports.

To guarantee access, the following steps should be taken:

• Utilize the "Global Mode" option found in the routing settings.
• Adjust the proxy configurations of the application. For instance, here is how to update the proxy settings for the LINE app:
  
  

• If you try to sign in on a new device and surpass the device limit, you will be redirected to the "Unbind Device" page, allowing you to remove any linked devices.

We have observed that some users find it challenging to select a server after picking a region.

To streamline the experience, we now display only regions. Heibao will automatically connect you to the best-performing server within your selected region. Here are the details:

• The location menu will show only regions, but each region has hundreds of servers. When you choose a region, Heibao will automatically connect you to the server that provides the optimal performance based on your network conditions.
• If you are not happy with the server you are connected to, you can disconnect and reconnect to the same region to link with a different server.
• You can continue this process until you find a server that suits your requirements.

Typical reasons for network problems consist of:

• Slow local internet speeds (without utilizing a NPV)
• Elevated user traffic at specific NPV server sites

To address these concerns, you can attempt the following strategies:

• Verify your local internet speed by briefly turning off the NPV
• Experiment with various network connections like WiFi, 4G, or 5G while the NPV is disabled to pinpoint any connectivity issues. For instance, if your WiFi is inconsistent, consider switching to a mobile data connection.
• Disable the NPV, select a different server location, and then reconnect
• If you prefer to remain connected to the same geographical area, disconnect and then reconnect, as this might connect you to an alternative server within the same region.
• Keep conducting these tests until you identify the most appropriate server for your needs.

Global Mode: Enabling this option activates NPV for all online activities, which could result in slower performance for local websites and applications.

Split Mode: This option utilizes NPV solely for websites that are restricted due to geographical limitations, such as Google, YouTube, and Netflix, while preserving access to local networks for Chinese websites.

You can modify the routing mode in the App Settings.

If you encounter difficulties accessing specific websites or applications, consider switching to "Global Mode."
