Mobile app help

I have a React Native / Expo mobile app called BodyBrief th Back up now e. The codebase was built witn, Replit. The production AAB builds successfully via EAS, but sign-in is broken in production because the Clerk production instance isn't fully configured - the publishable key points at a domain I don't control DNS for. need someone experienced with Expo + Clerk + EAS to take it across the finish line and get it live on Google Play. Scope of work: Set up a Clerk production instance properly on a real custom domain (I will purchase the domain - please advise which to buy) Configure DNS records to verify the Clerk domain Create Google Cloud Console OAuth 2.0 credentials and connect them to Clerk's production Google SSO Add the correct redirect URL (bodybrief:///) to Clerk Update eas.json with the new pk_live_ publishable key and production API domain Run a fresh EAS production build (eas build --platform android --profile production) Verify Google sign-in and email sign-up both work in the resulting AAB on a real device via Google Play Internal Testing Help me upload the working AAB to Google Play Console and walk me through submitting for review What's already done: App is built and functional in dev Google Play Developer account exists App was uploaded to Internal Testing once already (broken build - needs replacement) Walkthrough/onboarding Ul is finalized Clerk production instance exists but is misconfigured What I'll provide: Access to my Replit project Access to my Clerk account Access to my EAS / Expo account Access to my Google Play Console I'll purchase the custom domain on your recommendation Requirements: Demonstrated experience with Expo + EAS production builds Demonstrated experience with Clerk in production (not just dev) Comfortable with Google Cloud Console OAuth setup
