You have not defined categories in your feed file for the tags you've specified. Did you define categories in the developer portal?
Exactly, the categories are defined on the developer portal, i just set the tags on the jSON feed.
If you haven't resolved this problem, you should consider defining your categories in the feed file. Defining them in the feed file means you have only one place to manage your feed file. And, if I remember correctly, defining them in the developer's portal can be somewhat klugy.
The issue still persists.
Strange because in the preview the channels looks good:
PD: channel is not published yet.
