   },

I hope you are using Facebook.logInWithReadPermissionsAsync . If so,

Add behavior: 'web' as below.

It worked for me in Expo client and production as well.

Facebook.logInWithReadPermissionsAsync(Config.loginSetup.facebookID, 
 { 
 permissions: ['public_profile','email'],
 behavior: 'web'
 })
