I have downloaded music. I want this music playable offline on my mobile device. Its in "local files" on my vomputer. I have made a playlist for the mixtapes i want, set it to offline mode on my computer and on my phone. The devices are on the same WIFI, i even tried connecting mobile to pc using micro usb. Both spotify entries in my win-firewall is accepted private and public. There seems to be a problem on spotifys side and i would like some help. This service costs to much for things not to work.
