Podcast episodes not showing up

I have been podcasting for a while, I use LIBSYN as my host and upload to my website. I have always had the shows show up on my website and itunes no problem. Since Feb. 24, my episodes are on LIBSYN and my site but not on itunes and I can't get a straight answer why not. I have already checked in the new itunes podcast connect, it shows my podcast is active and when I try to resubmit my feed it says it's already been submitted. Anyone got any ideas?
