Describe the bug

I had already opened this issue in Amplify-UI originally, as I thought it was a bug with the UI component. However, upon further exploration we noticed it's a general issue.

In particular, auth functions such as signIn don't work in the release (production) versions of the app. We are using expo. In the development builds, everything works as expected. When I create a release for example with npx expo run:ios --configuration Release the functions stop working (clicking on the login button nothing happens). I have checked AWS cloudtrail, and I do see that Cognito indeed receives the requests, and answers successfully. I have tried both the SRP and PASSWORD. Auth flows, but neither works. The issue happens both on iOS and Android.

Expected behavior

Login function should work the same in release as in the development builds

Reproduction steps

1. Build the app with npx expo run:ios --configuration Release
2. try logging in with an existing user

Hello, @Catazza 👋. We'll close this issue as a duplicate of #13587 since that was transferred from the UI repo. We can reference anything from this issue if needed, but we'll follow up with further on the other issue. Thanks!
