Need Firebase Expert to Deploy Updated App & Enable PWA

I have developed an app using Firebase Studio (Firebase Extensions & Hosting + Firestore backend). The app is already live, but after making some updates, I’m facing issues deploying the updated version.

Even after trying support from AI assistants like Gemini, the deployment is still failing — and I need an expert to:

Fix the deployment issues

Get the updated app live again

Enable proper PWA (Progressive Web App) support so users can install and use the app like a native app on mobile and desktop

What I need:
Firebase expert who can debug and deploy updates

Help configure service workers and manifest for proper PWA functionality

Fix any permission/policy or hosting-related bugs

Walk me through the issue briefly so I can avoid this in the future

Tech Stack Used:
Firebase Hosting

Firebase Firestore

Firebase Authentication

Firebase Studio (Visual editor)

Deliverables:
Live updated app deployed successfully

PWA fully functional (installable, offline support if possible)

Optional: A simple document or screen recording explaining what was fixed

Timeline:
ASAP (urgent deployment required)

Budget:
Flexible, based on experience and speed
