Anyone using Meadow with AWS?

I have been trying many things off and on for the last week with regard to certificates to use with an MQTT client, but getting things into an X509Certificate2 for .NET is not working. I worry if I can get that working, then the next problem will be something with TLS 1.2 support… If anyone has pulled this off, I would really like to hear from you.

This is kind of bummer because there is much on the Wilderness Labs web site about the Meadow being for IoT devices and they even have the AWS logo there which seems to imply it has been made to work.
