The url of the feed has not changed and I verified it is working on both android and apple devices.
On the iPhone it was under shows and “add a show by url” entering
https://community.komando.com/feed/tkks/
Enter this URL, then enter your Komando Community username or associated email address, along with your password, when prompted.
Can you reboot your phone and try again when you get a chance and let us know how it goes?
