I embedded the Podlove Subscribe Button into my Tumblr-Site www.nachrichteins.de, which was very easy and no Problem. When I click on subscribe, the button opens and my Podcasts apperas. Everything fine. But when I click on next, to select an integrated App or Cloud Service, the upcoming Window is absolutely empty.
I am using Soundcloud as Host and this is the URL of the Feed:
The Feed is working fine, I just tested it for the 100th Time. There are absolutely no Problems.
I am thankful for any help!
