Description of Issue

I was trying to get Roon Arc to work. In the process I tried to “open” the config screen on the Roon Core on the QNAP but every time I try to access the settings it opens a new window. In the window the only thing I get is a message “Not logged in!”

I have removed the Roon app on the QNAP, restarted the QNAP and re-installed the app again but it did not make any difference.
