I've been living this exact nightmare for three weeks now. Support ticket's been open the whole time - still nothing. Purchase event used to sit at roughly 9, steady for years, and now it's hovering around 6. Nothing changed on my end. Campaigns that were profitable and stable just died overnight, never came back.
the spending is the real killer. it's barely spending at all, and one single ad is somehow eating 99% of the daily budget. Feels like the platform's completely broken and no one's even trying to fix it
