Hey @ezebs, welcome to the Community.

Hope you are doing great!

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 we might test could include the next generation of security protection, or new ways to listen. It's also a way for us to introduce new features, and fine-tune the app to be compatible with specific devices. 

Thanks!
