Shuffle feature in Vox Cloud


I am experiencing a problem with playing songs in shuffle from the Vox Cloud. Specifically you cannot use the shuffle feature with the entire library, but only by selecting an artist or an album. If you activate shuffle and play by selecting the entire library (or without making a selection), nothing happens. I think it’s a bug in vox cloud, because with iTunes library connected to Vox (with files stored on computer) everything works fine. Thank you for support.
