Changing TIDAL account; any tips?

I was going to create a new thread but am glad I found this one. This is my issue exactly and I learned the outcome the hard way - I changed the TIDAL account in Roon and lost my library. It’s not a big deal because I am trialing Roon with TIDAL for now. But it’s not what I intuitively expected.

What is the point of Roon database then? In my view the Roon database was a collection of pointers to tracks on local storage or a remote server. In my view there is not much difference between the in-house NAS and TIDAL as a remote server. The former doesn’t require a subscription, the latter does. Why did changing TIDAL login kill my database? It’s the same as changing my NAS password would kill my database. The tracks would still be there, only the password changed. Why kill the database?

Can the developers please look into the logic of this? An option to kill or keep the library upon TIDAL logout would be nice.
