Unable to add the selected tracks to the playlist on Android

Hello,

I have been experiencing this error on my Android 7.0 phone when trying to add new songs to the playlist (https://www.deezer.com/playlist/6209841564?utm_source=deezer&utm_content=playlist-6209841564&utm_term=2938404124_1565810170&utm_medium=web). I have already reinstalled the app and cleared the cache and local files but the error persists. I have also checked I have the latest version of the app. The playlist is way below the top limit of songs.

However, when using the desktop version I can add them without errors.

Any help on the issue will be appreciated.

Best,

Mauricio.

The literal error is: "Unable to add the selected tracks to the"All_my_songs" playlist". It doesn't matter if I change the playlist.
