Hi ​@Egon Gross !

After reinstalling Deezer, you will have to re-download everything you previously downloaded from the beginning.

Does that mean, that all the previous Downloads were deleted physically from the according folder during the re-installation process?

​@Egon Gross downloads are device-specific and are stored as data on the phone itself, so when you delete the deezer app from your phone, all data goes with it.

So you need to reconfigure all your settings and re-download any music you want for offline listening.
