I've been searching any docs I can find for the past few hours to no avail, so I figured I'd just ask here.
I adapted the Food Network and HGTV channels into two new channels for two channels with similar website structure, and now just need to change the icons. However, I can't figure out how their channel icons work as there are no icon-default or art-default files as I would expect. Looking into it, most of my updated major channels (ex. ABC, NBC, HGTV, Food Network) no longer have icon-default and art-default. Did the standard practice for channel icons change? How do channel icons work now? Where do I need to put the icons for channels now?
