Lumin Ap on Lumin players - not so good?

This should not be so challenging. I bit the bullet and signed up for Roon to feed my T2 using my iPad to listen to Tidal.  Roon is looking for my Roon Core. What the flip is that and how do I access it?!

Isn't my Lumin the "core"? 

the core is where the roon operating software sits. It can be on your computer or a nucleus or a server.

You need to connect the app to the core via ethernet or wireless.

As an example, An iPad would be an endpoint.

So the Roon Remote and Roon Core are two separate entities each of which require a subscription?! Not the most easy of platforms to install or understand...

No it's one subscription.

You just have to have both pieces working together that's all.

Yea it's confusing. Talk to the guy sold you the t2

I own the X1 because I liked idea of not getting a separate dAc.
