Hi ​@Susanna Nielsen !

To resolve Deezer download issues on your Android phone, try clearing the app's cache and data, reinstalling the app, ensuring you have a stable internet connection, and confirming your Deezer account is a Premium plan. 

Also, check that you have enough device storage, that you are downloading favorited tracks or playlists, and that your phone's battery saving mode is off. 

If the Problem Persists Contact Deezer Support providing details like your device model, operating system version, and the Deezer app version.
