Mission350: ios data contains duplicate

[Futabay]

Hi,
Based on Kaggle discussion, it seems that there are two duplicate data ('Mannequin Challenge', 'VR Roller Coaster') in the data set.
Here is what I did to remove the duplicates:

Can confirm that the issue still exists in this project.

In the guided project instructions on page 6 it says:

In the previous step, we managed to remove the duplicate app entries in the Google Play dataset. We don't need to do the same for the App Store data because there are no duplicates — you can check that for yourself using the id column (not the track_name column)

This is not true, as the id column specifies an id number, while the track_name column specifies the actual app name which should be used to detect duplicates.

Probably the author used the id column, found no duplicates based on the id (which is correct) and then moved on, but instead he should have used the track_name column.
