We are using PowerPress for Wordpress website and successfully published two podcast channels. However, now after we went live with the client's new website - his new podcasts are not showing up and not able to subscribe to these podcasts from iTunes. Only showing the 3 instead of the newest one #4 and not able to subscribe.

We have tried establishing the new URL feed and 301 redirects but nothing seems to be working - have waited 3 days with no improvement.

What is next??? Any way for someone from iTunes to just troubleshoot this? How do you connect with anyone directly?

Thank you,

Angie
