I’m more partial to PocketCast app. Its not free, but it is only a modest cost. But besides Soundbytes, it has a library of thousands of podcasts around the net. I found one such cast that I’d never heard of prior that I now follow religiously because its so good.
I’ve used the paid version of Beyond Podcast for years to listen to Soundbytes.org and last month it stopped getting the feed update. I get a message saying it’s not a valid feed. Has something changed in the feed address?
