We have auto-renewable subscriptions in our app with introductory offer (3 days free trial). The problem is that we experiencing some really strange metrics in our trends reports (Sale and trends). We started our ad campaign with different sources. As a result, we got 500 subscribers with introductory offer. The problem is, that when trial ends, almost all subscribers moves to "Billing retry" state. Almost 95% of all subscribers. It's not a "Cancelled" state, it's exactly problem with billing (Apple cannot charge money from a card or something went wrong with payment). We believe that this is abnormal. A few days after we started a whole new ad campaign with independent new sources. Same result. 90% of subscribers in "Billing retry".
A few tickets to Apple support. Without results. Default responses with public documentation text.Its a new app, so we do not have any metrics to compare with. Does anyone have any idea what it might be? Guys, we really stuck :( Could there be a problem on our side (in code or maybe with AppStoreConnect purchases settings)?
