Hey Everyone,

To resolve significant reliability and performance concerns associated with the WireGuard VPN client on the M8550, our engineering team has produced a specialized firmware update. This release addresses configuration parsing errors, strengthens connection stability, and optimizes traffic routing efficiency. 

Applies to:

M8550(EU/US)_V1.0/1.6

We recommend installing this beta firmware if you happen to experience any of the following behaviors:

• Configuration File Import Error: 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 cannot pass properly between the client and the remote WireGuard VPN server.
