Missing songs in my playlist song since update

[katieh_64]

Since the newest update I've noticed that a lot of songs are missing from my playlists and in some of them whole albums are gone. I've checked and they are all still on Spotify and when I go to add them again it says they are already there but they're not. Has anyone else had this problem and do you know how to fix it? I've  tried restarting my phone etc but nothing seems to be working
