For all of my songs that are only documented on the Cover Art Archive, the cover art isn't showing up on the application and the website. The problem came out of nowhere a few months ago and is diagnosed as a "CAA JSON error: expired connection", which I'm sure is only affecting CAA since fanart.tv and TheAudioDB work just fine for all their documented songs. Nothing within the PC has been tampered with and Picard still works fine when tagging songs to their respective albums, making the problem almost impossible to trace from my perspective.

P.S. Musicbrainz just started displaying the cover art correctly a few days ago, but the problem is still persisting with Picard
