Unable to download episodes

[der werte Herr 0]

I am a big fan of the first season and just learned about the second one. I couldn't be happier! I'd like to download the episodes to listen while jogging. Unfortunately, the download button doesn't work for me. Does anybody have the same problem? I am happy to use Stitcher Premium if that allows me to download - but from the description of the service I couldn't find out if going premium enables downloading.

I'm grateful for any help on this issue
