No way to change music categories in adaptive mode
In wide(-r) window Lollypop has a menu that opens after clicking a three-dot icon, that lets you choose (enable and disable) the music categories (Artists, Albums, Playlists, Web etc.). After narrowing the window the button does not work anymore.
This is especially an issue on mobile devices (such as Pine64 Pinephone) where the application is in adaptive mode at all times.
