Renewal trouble rarely shows up as a single number. A trial converts, then the first paid period refunds. Billing retry catches some people in Indonesia and almost none in Malaysia because the payment method mix is different. The lapsed paywall still offers the same introductory week, so returning buyers wait you out.
This briefing is only for apps with auto-renewing subscriptions. Consumable-only catalogues should not buy it. We read a quarter of renewal and refund reports if you have them, or a month if that is all finance will release.
You leave knowing which renewal week is the actual leak, whether the grace period is doing any work, and whether the win-back offer is teaching people to lapse on purpose. We will not write the win-back email for you; we will say if that email contradicts the store paywall.
