Spotify - album artwork

I bought a Uniti Atom recently for my house. I have already owned one for about a year, which i keep at my office. Love it so much i bought anotehr for home!  But having a weird issued with the new one. For some reason, on the home unit, when I play a song on Spotify, instead of getting album artwork, I just get the Spotify logo. Any idea why? I have tried different songs, tried playing from different sources (phone, computer) but still nothing but a big logo. I have only had it a few weeks, but pretty sure it was working when first installed. Has anyone else experienced this issue?  Any suggestions? Thanks.
