- Sorry, I don't know about publishing updates. I've actually wondered the same thing. My first channel is still under review for being published the first time.
- If you change the URL of your JSON file, then you'll have to update the Feed URL. If you're just updating the contents of your JSON file, then you don't need to do anything. Roku will periodically re-download your file and update your channel with any new content.
Thanks for your reply. As you have pointed out, I have confirmed that I don't have to do anything after updating the contents of my JSON file. The updated content does appeared shortly thereafter on my channel.
I also just updated my Categories. This however requires you to Publish again which then goes into the review process again before actually being published.
