songs are greyed out or playing wrong version/mp3's not showing album art anymore

Hi,

• Loads of songs are greyed out in favourite tracks and other playlists and sometimes even in artist pages. the only way to play them is by looking up the song and play it from the search page. the songs that are greyed out are always the same songs (for example “secret story of the swan” by “iz*one” or “whistle” by “blackpink”) even when logging in to a different account or using a different device.
• Some songs are playing the wrong version when i play them from my playlists. for example if i click on the korean version of “as if its your last” by “blackpink” it will actually play the japanese version intstead of the korean. the only way to play the correct version of all the songs that are playing in the wrong language is by going to the artist page and play it from the album the song is in. the weird thing is that is the exact same song as it will say that the song is in my favourites, but when i play it from the artist page the language will be correct.
• Most of my Mp3 files are not displaying album art anymore when i add them to my favourite tracks or other paylists. when i head over to the mp3 section i am able to see the album art tho.

The reason that im puting all 3 three issues in one topic is becuase all those issues came after the same update. first i was using the beta version of the app on a android phone. downgrading the deezer app to the stable version fixed all the issues, but a few weeks ago these issues came back at the same time after an update of the stable app . downgrading the app to an older version fixes it tho.
