Comment 2 for bug 887482

Michal, thanks for explaining the feature was never implemented.

I was given the impression the functionality existed because of reviews like http://www.ubuntu-unleashed.com/2011/04/ubuntu-one-music-on-android-just-got.html and http://www.omgubuntu.co.uk/2011/04/ubuntu-one-music-android-app-adds-new-features-support/ , which were apparently incorrect.

Does anyone know of a possible workaround to delete existing playlists?

To comment on your workaround for editing, by the way, I must elaborate that I had already tried saving over an existing playlist with the same name, but it did not overwrite the previous one. Instead, I now have 2 playlists with the same name.

Can't wait for the revamped UI to be released!
