I was led to believe when I purchased my Deco M5 home mesh system that it was compatible with VPN setup (in particular Nord VPN). When I follow instructions to install the VPN using the Deco app or by logging into the mesh I cannot find the appropriate menu location under "Advanced" to do the installation. 

The Deco app version is: 3.7.83

Is there a different version of the app that allows for VPN installation or was I misinformed about the capabilities of the Deco M5?

If the M5 is compatible, how do I install my VPN when neither the app nor the main login to the device does the correct setup menu?
