M8550(EU/US)_V1.0/1.6

Hi All,
To address critical reliability and performance issues with the WireGuard VPN client on the M8550, our engineering team has developed a targeted firmware update. This update resolves configuration parsing errors, enhances connection stability, and improves traffic routing efficiency.

It is recommended to install this beta firmware if you happen to experience the following situations:

• Configuration File Import error: Users are unable to import WireGuard VPN configuration files due to parsing errors or unsupported parameters.
• Connection Failures: After the configuration file is imported successfully, the VPN tunnel fails to establish a stable connection.
• Traffic Routing Issues: VPN Client status may display "connected", but VPN traffic can't pass  properly between the client and the remote WireGuard VPN server.
