I had a Polo withdrawal sit all night long in pending status. tried 4 more times since, nothing. BTC withdraws just fine. Not making me happy. 
Yeah, I've been withdrawing everyday for a while at my limit and no problems. Problems started about 2 days ago.
I'm thinking I'll need to convert to BTC and Shapeshift once its out. It's then abou short term timing. Grrrrr
