For this bug, I’m specifically talking about Deezer’s Sonos integration inside the Sonos S2 app. My Sonos app is up to date (version 16.1) running on an iPhone XR (iOS 17.4).
I’ve noticed that, despite my Deezer country selector being set to United Kingdom in my Deezer app, I’m seeing foreign language playlists recommended on the landing screen of Deezer’s Sonos integration inside the Sonos app, under the “Music by genre” and “Music by mood” headings.
Why I think this is a bug, and not an intentional feature
Because these foreign language playlists are only displayed on the landing screen of Deezer’s Sonos integration inside the Sonos app.
They are not displayed if you tap the “Music by genre” or “Music by mood” headings. You are then taken to a full page view of these recommended playlists - all of which are in English.
The foreign language playlists are also not recommended inside the Deezer app.
