Different iPhones, different interfaces

[user-removed]

I have Spotify app installed on an iPhone 6 and iPhone 7 but each has a different interface.  I've checked the versions and both are running 6.8.0.3786.  On iPhone 6, there is no "Your Library".

On iPhone 6, I've deleted the app, downloaded and reinstalled again but no change.

Is this normal?

if i'm correct iphone 6 should have the my library feature, it's normally located on the bottom right corner of the app.
