Hi @Chrisbradshaw 

I dot know why you can't find certan albums . I was find all original albums of AC/DC  .

Here is AC/DC all Original Album Collection

Hi @Chrisbradshaw could you please confirm if this happens on iOS or Android app?
Thanks 

I’m on iOS and not a single artists now has a full discography- you have to search for the album to find it.

Queen have no original studio albums in the discography, for example

I just tried it on my iPhone SE.I’m able to see the full discography of Queen.

What happens when you use Deezer on a browser? Can you see everything of not?

@Chrisbradshaw !

Queen have full discography ,but you need, like you say search for album to find it !

Except there is situation when for some reason album is not on Deezer .

Below is link why is so :

Hi @Chrisbradshaw, thank you for sharing this information.
In fact, we have received in the last few days some complaints from users reporting the same problem, but only in the iOS version.
In the Beta 9.44 version and normal version, the situation has already been resolved and the display of all content appears.
