Mission matching flow

What changed

01
Payments
Before
Settlement broke every time payment gateway rules changed
After
Switched gateways four times, redesigned settlement, and landed on in-app purchases.
02
Refunds
Before
Users spent credits and then got refunds (refund events weren’t received)
After
Within 3 days: a refund webhook plus automatic credit clawback.
03
Release
Before
Two App Store rejections, and every fix meant another review
After
Moved to OTA updates so fixes no longer wait on review every time.
04
Security
Before
Security gaps in code built quickly with AI agents
After
A full audit four months in blocked 4 critical issues.
