2 years on and still getting this error on certain songs in my favorites playlist using the Windows app.

It wouldn’t be so bad if it just skipped the songs, but no, it stops the entire playlist until I click ok

Horrible user experience

It drives me nuts! I can't use Deezer like this.

Webapp through Rambox.

I understand your frustration, It also happens to me once in a while on desktop app.
It is hard to reproduce though and it would be very helpful if you could tell if there is any pattern (i.e: every certain number of tracks) or if it happens always with the same tracks, etc.?
Thanks 

For me it happens randomly. Sometimes it's all tracks, sometimes it's a bunch of them and sometimes it's just one. The first track in a list usually works.

I used to be able to refresh to fix it, but that no longer works sadly.

The interface will tell me it's ‘now playing’ but it's not.
