Hello,

after updating the iOS app to the 7.4.0 version (and 7.5.0 as well), my playlist keeps playing in the wrong order if I sort it by artist or recently added, while if I sort it by custom or by title the songs' reproduction is perfectly ordered.

Of course I have the shuffle button disabled.

This issue is only on my iOS app, on my desktop version everything is normal.

I tried sorting the playlist by artist on my desktop and copying it in a new playlist so the custom (which is the default sorting order) and artist sorting order would correspond; but if I add one single song (e.g. "Chicken" by Jaco Pastorius) and I try to sort the playlist by artist, the reproduction goes crazy after the letter J (as for Jaco Pastorius, the artist I added after the creation of the playlist).

I'll make an example as clear as I can (see the attachments)

As you can see, in picture 1 is depicted the playlist order as sorted by ARTIST, while in picture 2 the queue skips the song "Mojo Pin" and plays it once that all other songs from the album have been played.

And this is just an example, if you go on in the playlist (spotify:user:nonnoteo:playlist:4cVhxjiv5g4hdEx5X8NY9Q) after the letter J you'll see many other examples.

Any suggestion? I hope you'll fix this bug in the next update (which I hope is soon to be released).

Thanks for the patience, I hope I've been clear enough!

PS: I'm on an iPhone 6 with iOS 10.2.1 with a Premium Spotify account!
