@Gimmick @Mondauthor I'm not sure about the protocol in these situations, but assuming you've already uploaded a preview file, I guess after a few more days you could message a Portal Mod or someone about it - although I'm unsure if mods have the power to deal with approving ads.

I believe it's usually a matter of time for ads to be approved - how long has it been? Some of my games took up to a fortnight, but that was in the past - can't say what it's like now.

Been roughly ten or twelve days. Which includes the Memorial Day three day weekend. Still being patient. Maybe this week.
