Welcome to the Party!
I've had the same issue for the past 4 weeks, and have gotten the same emails everyone else got.
Although I must have been at the tail end of "Morgan's" email list as I essentially got the "don't call us we will call you when its fixed" response.
I work in the IT field, and I can tell you anytime someone says we need to get the engineers involved, your looking at months of work. That's code review, code fixes, testing in development and QA environments, and perhaps even some regression testing all before code fixes can be deployed to production, it's just a slow moving process.
Like glacial slow! Polar icecaps melting slow.
From the consumer side, this *****.
They have the market cornered on services, and we can't get in.
I'm in the same boat as the rest of you.
It's to the point where I want to tell apple to go pound it and move on, but I wont..... because I want my podcast in iTunes, and they know that. It's just the way it is.
I can confirm that as of this morning, it's still broke.
What I can add however, is that I have been testing daily, and I am getting errors at random new points that I wasn't getting before, so it does atleast appear to being worked on.
And the wait continues.......
See ya all next week, or see you in iTunes... whichever comes first.
***** UPDATE*****
To other Libsyn podcast hosters....
I can also confirm that Libsyn is willing to list the show for you using Libsyn's master iTunes account.
It will get your show instant iTunes approval, but you wont have access to your shows stats on iTunes, as it will be listed under Libsyn's master account and not you own. Libsyn is willing to provide you screen shots of your shows usage in Itunes, you just can't access them on your own.
You would always have access to your shows Libsyn stats, but you would lose visibility into how much of that is coming from iTunes without asking Libsyn to provide those stats for you.
So... you can get it, but it might not be ideal for some of you.
Libsyn has been a great host for me, they are VERY economical, super fast to respond to emails, and might provide an alternative to this looping issue for some of you that want into iTunes now!
Host with Libsyn, and email ROB at Libsyn and your problem is solved.
I'm choosing to wait it out for now.
