Android 14 - no download of favorite songs, storage change not working...

Hi there, I am using Deezer app on Sony NW-A306 MP3 player with Android 14 and 1TB SD card. There is no download favourite song option anymore for last few months - I need to go to the album page and download the whole album, then if i’am lucky some songs are downloaded. I lost hours doing it, and eventually it gets erased. 

Also, the application is not registering anymore when you change the storage to external memory. 

When I want to play favourite list I am getting 90% of time “Error: Failed to play. The requested content is not loading.”

My intention is not to download music and go offline. It is not possible technically to steal the format. Otherwise I wouldn’t supporting Deezer. I just need a reliable app on Android 14. I know Android 12-14 versions are extremely slow, but last year the app was normally working.

I tried every possible tweak written on Reddit, nothing helps. 

Does Anyone have the similar problem? 

Thanks!

Best,
