Using Roon in different locations

Hallo, I have difficulties in switching my licence between the two Roon servers (both are Nucs) I alternatively use when I move from one to the other houses where each of them is located.
In particolar, when I need to switch, the app asks me to connect to the new server detected on the network ( which appens) but does not simoultaneously asks me to disconnect from the previous one. This request appens after a significant time and I do not not why. Meanwhile, I cannot access my connection to Tidal or to other music sources.
How can I avoid this and have a simoultanes access to the new server and disconnection from the previous one?
Thank you for advice!
