I am running Roon 1.7 remote on a new 16 inch MacBook Pro (running macOS 10.15.1). Using the option (in Preferences > General) “Allow more for covers and photos?” has no effect—save that initially more albums are displayed for an instant when Roon starts (four rows of smaller cover art) but the screen immediately zooms to show only three rows of larger cover art.
I’d be interested to know if anyone else sees a similar problem.
