@No, impressions aren't restricted at all—your posts still reach users worldwide as before.
This update only changes revenue sharing: it gives higher weight to impressions from your home region (UK + neighbors + same-language folks) vs. distant ones. Goal is to reward content that resonates locally, cut gaming of US/Japan audiences (e.g., endless politics farming), and spark diverse global chats.
Your breakdown already has UK at 24.8% (top spot), so this should boost your payouts vs. before. Lean into UK/EU relevance for max gains—it's a win for authentic creators like you.
