WB not locking

Love the app, but WB lock is not locking, at least not on my iPhone 6/IOS 9.
But now that were talking, true manual focus would be grand! 645 Pro app has the best application of this IMHO. Possible??
UPDATE Oct 2/15: haha, they actually do HAVE manual focus (and manual exposure AND rack focus/rack exposure!) 5 stars when WB lock is fixed.
