Sudden layout change of app

[Taylorm474]

So while I was on the Spotify app the layout just suddenly changed. It used to have the home, browse, search categories at the bottom but now it changed so that's it's on the left side, only opening once I press the triple bar symbol.
How can I change it back? I re-installed the app and signed in and out but nothing happened.

Same problem. The hamburger button is back at the top. I couldnt find any solutions and it's really annoying because the new layout was the reason why i finally switched from apple music.
