I'm still getting the same issue.
I've tried on three different PC's with iTunes 12.7.1.14, one running win 10 and two running win 7.
I've deleted the Pokercast, redownloaded the Pokercast, unsubbed and resubbed, all to no avail.
None of my other subbed podcasts do this.
This is the error message :
And when I copy the Pokercast URL this is what I see :
https://pokercast.twoplustwo.com/pokercast.rss
Is this URL correct?
I will always remain loyal and find a way to hear the show but thought you should have this info.
