Fix Mobile Sign-In Error

I have a live mobile music app that needs a short round of improvements before the next release. The highest-priority item is to add Sign in with Apple alongside Facebook Login so users can authenticate seamlessly on both iOS and Android. You should handle the full flow—SDK integration, callback handling, token storage, and a quick UI toggle on the existing welcome screen—without breaking the current email-password option.
You need to fix the google sign.
When you login the app, you can check confirm link on your mail.
but current it's now working.
so you need to fix it.
Fixed Budget : 20 USD
