Building a music Player

I was working the lesson and following along with a youtube video. My screen refreshed itself and now the lesson is diiferent from a moment ago.

Secondly I was on step 43 and now it says I am on step 49 and I am missing earlier steps.

Has this been an issue for anyone eles?

There were updates made to the project recently here

Since new steps were added, that is why the steps changed.

The new steps added were to better explain how arrow functions work.
So if you have a good understanding of arrow functions, then you can continue with step 49.
