Spotify App Suddenly Stopped Functioning - Version Issues

Hey everyone, I’m having a weird issue with my Spotify app. Yesterday everything was fine, but today when I opened it, the app just won’t work properly. It keeps showing me a message saying I need to update the version, and none of my music library shows up anymore. The strange thing is that my friend has the exact same app version and hers works perfectly fine. I did get an email from Spotify a while back mentioning something about older versions being discontinued, but I’m confused why the same app works for her but not for me. Has anyone experienced something similar? What could be causing this difference?
