Ubuntu 20.04 here, running version 18.104.22.1688.gf9a83c60 as a snap package.
Have recently noticed that after coming back from a period of inactivity, gnome-control-center starts freezing with 100% CPU and the wireless network slows to a crawl. (Bluetooth is maybe also messed up but I haven't investigated systematically.) My dmesg is also full of 'apparmor="DENIED"' messages with the interface "org.freedesktop.NetworkManager" and label "snap.spotify.spotify." Quitting spotify appears to solve this problem, though it segfaults as described in another thread. I don't remember this ever happening before updating spotify and it's happened a couple of times now, though it could of course be another update installed around the same time.
