I know it sounds simple, but it's often overlooked. Could you try restarting your device? If that doesn't help, try a quick clean reinstall of the app. Just follow these steps.
Also please note that at Spotify, possible improvements and new features are often being tested. This means you might see something on the app your friend doesn't, or get a brand new feature for only a temporary period.
Things tested could include the next generation of security protection, or new ways to listen. It's also a way for Spotify to introduce new features, and fine-tune the app to be compatible with specific devices.
