I've noticed it stopped working after I upgraded to marshmallow OS on my HTC M8.

I have the phone on the same wifi network, AND also have it connected to the PC via USB, but it refuses to download local files from the PC.

I have both Spotify apps open (PC and Anddroid).

I have the storage set to my SD card on the phone.

I've tried reinstalls of the app on the phone, wiping the cache, and toggling the download offline switches, but it won't copy over the local files.

It has no trouble downloading the streaming songs quickly.

😞 Please help. This is the main reason I keep using Spotify and paying premium - for these downloads.
