The split mode feature in Shadowsocks NPV for China accommodates web applications such as Telegram, WhatsApp, or Gmail, which utilize HTTPS. This mode can modify the routing for both HTTP (port 80) and HTTPS (port 443), enabling access to the web interfaces of these applications. However, the application versions might employ different ports.

To guarantee access, the following steps should be taken:

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

• When 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 disconnect any linked devices.

It's not uncommon to forget usernames or passwords, and we strive to simplify the recovery process. Here are your options:

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

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

• The location menu will only show regions, but each region includes hundreds of servers. When you choose a region, Heibao automatically connects you to the server that provides the optimal 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 linked to a different server.
• You can continue this process until you find a server that fits your requirements.

Frequent reasons for network problems are:

• Local slow internet speeds (without utilizing a NPV)
• Increased user traffic at specific NPV server sites

To address these issues, you may consider the following approaches:

• Assess your local internet speed by temporarily turning off the NPV
• Experiment with various network connections like WiFi, 4G, or 5G with the NPV disabled to detect any connection issues. For instance, if your WiFi connection is inconsistent, change to a mobile data network.
• Disable the NPV, select a different server location, and then reconnect
• If you wish to remain connected to the same geographic area, disconnect and reconnect, as this might connect you to another server within the same region.
• Keep performing these tests until you identify the optimal server for your needs.

Global Mode: Enabling this option activates NPV for all online activities, which might hinder the performance of local websites and applications.

Split Mode: This configuration applies NPV solely to sites that are restricted based on geographical location, like Google, YouTube, and Netflix, while allowing local network access to Chinese websites.

You can modify the routing mode in the App Settings.

If you experience issues accessing certain websites or applications, consider switching to "Global Mode."
