Ever since Spotify wrapped 2021 came out, my nest devices no longer play my personalised playlists via voice commands. I can see the command come up on my next hub (eg hey Google Play my playlist top songs 2017), but it simply ignores it and plays something that sounds similar. People are reporting this issue on the Google community forums too.
Thanks for reporting this issue to us.
We're aware of an ongoing issue affecting Google Assistant users - where they request personal playlists like "Discover Weekly" or any other user created playlist through Google Assistant, but a different playlist/album with a similar name is played instead. This is also being investigated by Google.
