Since adding n album from tidal last week, every album from that point forward uses that same album art. I;ve rebooted and I;ve manually gone in to edit. The correct album is found when I go to edit and I save it, but when I return to regular room display the same incorrect artwork is displayed. The music is correct, just the cover art is wrong.
Try this, it worked for me with the same problem recently. You may also need to redentify the Tidal albums already added which have this problem after you have cleared the cache.
