1) similar problem here in version 126.96.36.199. In the previous version 188.8.131.52 (probably) I could get my custom genres in the Favorites pane, because the current Genre was listed at the top, and tapping led up to the genre list, I obtained a list with (All, genre1, genre2, genre3).
2) I do not find the Group by option that is mentioned as New feature.
3) the new backup and restore does not work for me. However the old-style restore worked after that. Android 4.2.2.
At this state I cannot be happy with XiiaLive Pro 184.108.40.206, and can't go back to XiiaLive Pro 220.127.116.11 because it was protected from backup.( Actually I was able to get the XiiaLive Pro 18.104.22.168 apk and it installed and activated, and I would not prefer to do that)
