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

To make this easier, we now show only regions. Heibao will automatically connect you to the top-performing server within your selected region. Here are the details:

• The location menu will solely showcase regions, but each region consists of hundreds of servers. When you choose a region, Heibao will automatically connect you to the server that delivers the best performance based on your network conditions.
• If you're not happy with the server you're connected to, you can disconnect and reconnect to the same region to be connected to a different server.
• You can repeat this process until you find a server that fulfills your requirements.

Frequent reasons for network problems consist of:

• Slow local internet speeds (when not using an NPV)
• Increased user traffic at specific NPV server locations

To address these problems, you can attempt the following approaches:

• Verify your local internet speed by temporarily turning off the NPV
• Experiment with various network connections like WiFi, 4G, or 5G while the NPV is disabled to pinpoint any connection issues. For instance, if your WiFi is inconsistent, consider switching to a mobile data connection.
• Disable the NPV, choose a different server location, and then reconnect
• If you prefer to remain connected to the same geographical area, disconnect and reconnect, as this may connect you to a different server in 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 may result in slower performance for local websites and applications.

Split Mode: This configuration employs NPV exclusively for sites that are restricted due to geographic limitations, such as Google, YouTube, and Netflix, while ensuring access to local networks for Chinese websites.

You can alter the routing mode in the App Settings.

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