Seeing this on my channel right now as well. Preview version in the developer portal looks fine, but only seeing "Search" and "About" buttons on device. If it matters, I'm using the Showcase feed URL from Vimeo: https://vimeo.zendesk.com/hc/en-us/articles/360026953671, which doesn't allow me to really customize how the JSON is returned other than the options I can configure through Vimeo's side.
I'm also seeing this problem on a channel that had this problem in the past, was fixed by Roku, and is now plagued by it again. If you haven't already, please contact Roku Partner Success. If enough people complain, they may realize that Direct Publisher has some serious problems.
