I am also experiencing this issue on my iPad and iPhone. I have to close out the Roon app for it to fix itself. I can select a song to play. It plays, but when I go back into the app it is frozen.
I have this problem on my iPhone 15 Pro Max, but not with either of my iPads (2nd gen Pro) and 1st gen Air
