We're receiving reports about the Refresh button under the Recommended songs section under a playlist not working properly. Sometimes it just shuffles the already listed songs, and sometimes it just doesn't do anything at all. The list is only refreshed after actually adding a song to the playlist. If you're experiencing this issue, make sure to add your +Vote to this Ongoing Issue thread.
Thanks for your patience while we looked into this issue.
We’re happy to say that this should now be fixed for everyone! Just make sure your app is updated to the latest version.
If you're still having trouble, make sure to post a new thread in the relevant help board here.
