Can you give us some examples of those songs?

Elle Fitzgerald, Cheek to cheek

Ray Charles, Here we go again, You don't know me,  Fewer

Hi @Betouser !

Can you send us a screenshot so we can see more easily what the problem is !

From Deezer Help Center :

If content is greyed out and won’t play, it may be because you're not connected. See our Can't play music page for more details. It may also be greyed out because it is no longer available. This can happen if licensing agreements with the artist, label or right holders have changed.

Also note that playlists created by Deezer, other users and content creators may have had their content removed from public view.

Here are screendumps from two playlists.

Did you ask about it in the B&O community ? Since the problem is on their app maybe they can tell what the problem is . 

It only occurs in the B&O app, but I have found no help with B&O.

If the songs are playable on Deezer app I really don’t think the problem is deezer but B&O . Do you have any updates available to the B&O app ?  Try also clear cache for the B&O app 

You are quite right. It happened after B&O got involved with Tidal and changed the app. I hoped some had solved the problem here.
