It has been stated that .wma support was added in 2.3.0, but none of the albums that I have in .wma are even seen by Jaikoz. No error message given. Other albums in .mp3 in the same tree are loaded just fine.
Version 2.3.1 doesn't see multiple folders of .wma files
You misunderstood, wma support hasnt been added yet
