[solved] Subscribe button not working for downcast

While trying out the subscribe button with downcast on iOS I found out that it doesn’t seem to work at this time:
downcast creates a subscription and includes the downcast:// scheme in the url.
Therefore the feed never works.
I don’t know if this is a problem with downcast or the podlove subscribe button.
I’m using downcast v2.8.36.4584 and iOS 8.4

seems to be a regression bug in Downcast. we will probably remove Downcast from the list until this is resolved.

That might not be needed.
This is the reply I just got from Downcast Support:

Sorry about this, we have it fixed in the latest beta which we hope to submit late this week.

Thanks for the quick reply!
