Spotify does not quit properly and Album Art for Spotify Songs in Media Control missing

Problem 1:

When closing Spotify, the music stops, but the windows doesn’t quit. Clicking repeatedly gives me a "Force Quit" option, as Spotify has stopped responding.

Problem 2:

When listening to music via Spotify, (installed via snapstore; Premium Account) I can see and control the current song via the media control on the wingpanel.

However, I’m missing any kind of album art. I only ever get the default "music" icon.

I’ve seen in this post that the OP could see their album art from Spotify,
so I assume it must be something about my configuration.

Info:

Spotify is installed via the snap store, I have a Premium Account, I’m on Elementary OS 5.1.6 Hera.

I can’t recall ever not having the aforementioned problems, but just to be sure, all I remember to have changed regarding Spotify:

• I disabled the notification that occurs after every song in Spotify’s settings

Update: With a little patience, it seems, Spotify does close normally, although very slowly in my opinion. However, Problem 2 persists

Update 2: While Spotify’s still usable, I’ve taken the problem as a motivation to install mopidy with a spotify backend and iris frontend instead, which was admittedly a totally overblown solution.
I’d still prefer Spotify to work completely, as I’m stubborn like that, but oh well.

sudo apt purge spotify

sudo apt install spotify
