Provide a fixed-scope subscription integrity audit covering the complete journey from advertisement and onboarding through purchase, renewal, cancellation, refund, and entitlement removal. Test real transactions across devices and billing channels, reconcile each transaction against account access, inspect support escalation paths, and deliver reproducible failures with prioritized remediation instructions. An ongoing managed service can repeat the tests after releases and investigate unresolved billing cases.

Subscription fatigue makes unclear terms and billing mistakes especially damaging, while fragmented billing across mobile stores and direct payments creates more failure points. Recent reviews across numerous language-learning apps show the problem is persistent and category-wide rather than a single release regression.
