Sandbox Reset Issues?

A few days ago Metrc reset their sandbox environments for the integrators (like us). And they told us we'd have to reset the license APIs (expected) but that our existing sandbox service-keys would remain OK.

Now after the reset we keep getting "Authorization has been denied for this request." -- we've reset the license keys (as Metrc requested) -- and oddly the system have us back the same license-key we had before (was expecting a new one).

Our sandbox reset API call works as expected; an API key is delivered via email as expected but then the next calls to the API -- which should work (and have worked in the past) are failing.

Anyone else seen these types of issues?
