Replit Mobile App Deployment Guidance

I have a mobile app already running inside Replit; the next step is taking it live on both the Apple App Store and Google Play. I need clear, hands-on guidance—preferably screen-shared or well-documented—in setting up the entire release pipeline from Replit to TestFlight and the Play Console.

Key features that must remain functional in the published builds are:
• User authentication (email + social sign-ins)
• Push notifications (FCM/APNs)
• In-app purchases (consumable & subscription)

What I expect at the end:
• A repeatable build script or Replit-native workflow that outputs signed iOS (.ipa) and Android (.aab) packages.
• Step-by-step documentation of every store requirement you handle—certificates, provisioning profiles, keystores, app icons, screenshots, privacy URLs, etc.—so I can reuse the process on future updates.
• Brief guidance on post-release tasks: enabling analytics, crash reporting, and version roll-outs.

The codebase is JavaScript/TypeScript with React Native modules, so experience with Expo EAS or similar cloud build tools inside Replit will help speed things up. Let’s keep the process transparent: each major milestone should compile and run on my side before we move forward.
