I've been waiting for a fix for this since release. I get hopeful every time I read the Mage Hand Legerdemain description in game from the Notable Features section of the character screen as it still reads that "Your Mage Hand can stow away or retrieve objects carried by other creatures and use Thieves' Tools a range." Add to this that the Mage Hand description still has section for Mage Hand Legerdemain that reads as "When you cast Mage Hand, the spectral hand is invisible and can carry out additional tasks."
I would LOVE to see this fixed for Legerdemain to work as described. However, if they aren't going to fix it, at least spend the 30 seconds to remove the text from the descriptions so we can all move on and stop spending time researching it every week or so to determine whether it's been fixed yet .
