Meraki WAN Uplink Alerts

Hello,

I am looking for help with alerts for Meraki MX appliances, cant seem to find the condition that will allow me to alert when WAN 1 or WAN 2 uplinks go down. I also have a custom property for NodeLocation called Stores, and this is where all the Meraki appliances are located.

I use the interface down alert, and duplicate it, then I choose I want to alert on SD WAN Node, and then in my trigger condition as showb below, I dont see any interface name vlaue, or even a value for WAN uplinks etc.

I need to help please, this is for a big client and alerting needs to be accurate, as they have over a 1000 MX appliances that are being monitored.

thank you in advance for any help or advice.
