My Question or Issue

This only happens on Linux, but I keep getting the error that my library is filled up when I try to add a song to my liked songs. It works fine on my Android phone, Windows computer and Android tablet.

Actually, you can ignore this issue. Today after a reboot it works fine. I can't believe I didn't try rebooting yesterday... Sorry!
