Spotify has been consistently terrible on my Samsung smartphone and Windows 10 PC. Songs from the Spotify player won't play even when downloaded, playlists undownload, and menu options and playlists do not show up in offline mode. The only place Spotify works on is my iPad Pro (5th gen). However, if you pay for a service, you should be given equal access no matter the platform. There is definitely a lack of cohesion and testing between the teams working on the Android/PC versions.
