Mesh not working?

We’re trying to configure some of our beacons using the new Mesh feature via the API

It seems the API to create the mesh network is successful (it return to us a mesh ID), but we are both unable to use Mesh on the beacons, and when we query the API to list that ID, it returns NOT FOUND. Further, when we try to list all our mesh networks, it says we don’t have any.

I know this is a new feature…

Not sure if it’s related, too, but we also got a lot of API errors today - things that when submitted a second time seemed to be OK. Could that be related?
