System info: MotoG3 running Android 6.0.1 and Spotify Premium 8.2.0.788

I have noticed that since some time ago, the option menu entry All Songs disappeared on mobile, which renders me unable to play whole folders of playlists simultaneously. The only workaround I currently have is starting the playback of the desired folder via PC and transfer to my phone using Spotify Connect effectively forcing me to keep the playback on most of the time as too long idle times will cause the track to stop being on pause, hence I cannot continue the playback due to the issue described above.

Since folders were a major point in structuring my music library, I wonder if there is any possibiltity to still play a folder's contents from inside the Android app, as well as why that option disappeared so suddenly.
