I sent you an email response earlier as well. I know there is a lot of information in this thread, but there are setup steps and information for multiple apps in this thread. You mentioned you are using iTunes before. For iTunes, there are only a few short steps:
Choose “Subscribe to Podcast” from the File menu and insert the podcast feed URL: https://community.komando.com/feed/tkks/
Enter the username and password you use to log into this website (community.komando.com) when prompted.
That should be it!
You can remove the old outdated feed by selecting it and then hitting the Delete key on your keyboard.
Hope that helps!
