I've got a blanket rejection for my page regarding instant articles. Apparently I violated the monetization agreement at some point (though I collected no money at all, and didn't even have ads); and when I go to the page to appeal it, it's so broken it doesn't let me even submit my page to the appeal process. There's no other way I have to contact them at this point.
Yeah, strangely you cannot appeal if you haven't yet made it through at least once. At least thats how it appears. We're having the same problem. There is basically no recourse if there is a communication problem and you just need to contact someone to resolve it.
