I'm on Samsung Galaxy S7

I've tried all 3 subscribe links at the bottom of this page:

I've tried copying the links and pasting into a new feed, tried clicking the links on the page, all fail.

I searched within the BeyondPod app itself in the content page, and Software Engineering Daily does appear but when I try to subscribe from there it fails with message: This Feed Has No Content.

Help me Obi Wan...
