Flags — the regions we asked our observer pool for while recording this ad in this channel. That is a label on our request, not a confirmed place of viewing: when no account is available in the requested country the pool silently substitutes another and does not say so. It is not the advertiser's targeting country either. We stopped requesting the region on {date}, so newer creatives carry no flags at all. The channel's main country (by its language) is highlighted in blue; regions under 5% are collapsed into +N.
