In general, I always try to put my PM shoes on and try to evaluate what benefit they could possibly be receiving to ignore such a prominent issue that you can pretty much guarantee they are well aware of the issue.
That being said, I completely agree that this is pretty strange since I have not a single example that comes to mind in this case...
They could just be shitty devs? There's a reasonable amount of evidence for that: their android client is extremely buggy, and one day they deleted all my partner's playlists. On mac, I regularly have to close the client to force it to sync playlist changes, and sometimes playlist changes just disappear when I quit the mac client. I recently found 3.5g of old spotify updates sitting in ~/Library/Cache on an older, ssd space constrained mac. I have multiple performances of the same songs from several of my favorite artists; their client occasionally confuses different performances with the same name. You have to delete and re-add to get them to match correctly. I can continue...
