Has anything changed about the way we publish Office.js add-in to Office Store? I'm following the documentation (which is pretty recent) and in there they ask me to go to Partner Store, then Office Store tab and choose New Offer > Office add-in:

But in my Partner Center there is no Office Store tab. There is a New Offer dropdown but it doesn't contain Office add-in option.

I hear that they have merged the two (Marketplace and Office Store), but it doesn't seem to be the case right now. Or am I looking in the wrong place?
