What's new (v1.2.12)
This release improves onboarding reliability, startup behavior, and study planning accuracy. It fixes a paywall/session completion issue, improves offline fallback when iCloud sync is slow, resolves a dashboard hang, clarifies FSRS future load forecasts, and keeps “Too easy / don’t care” inside feedback where it belongs.
