New Nest Doorbell (wired) SDM Support

I received and installed the new Nest Doorbell (wired) over the weekend and wanted to play around with it today via the SDM API but I discovered it was not listed in my Device List and while "Nest Doorbell (wired)" is listed in the supported devices, it seems to still refer to the 1st generation Nest Doorbell (wired).

Is there typically a lag between launch and SDM API support for new Nest devices or have I missed a setting/configuration somewhere?

Thanks

I doubt it. Lots of other users are reporting the same issue (see this thread in the official help forum).
