Firebase returns no lead to ios testflight utilizing capacitor

Hello im utilizing nextjs with capacitor and have firebase authentication. every little thing works high quality on native configuration

import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  appId: 'com.xxx.app',
  appName: 'xxx',
  webDir: 'out',
  bundledWebRuntime: false,
  // No server configuration for manufacturing
};

export default config;

as quickly I swap to manufacturing configuration

import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  appId: 'com.xxx.app',
  appName: 'xxx',
  webDir: 'out',
  bundledWebRuntime: false,
  server: {
    androidScheme: 'https',
    iosScheme: 'capacitor'
  }
};

export default config;

on this configuration signInWithEmailAndPassword returns no outcome ( no success no fail )

that is the final community message im getting

URL: https://identitytoolkit.googleapis.com/v1/accounts:lookup?key=XXXXX
Standing: 200 OK
Supply: Community
Handle: 216.58.213.106:443

whats attention-grabbing tho is that if i enter unsuitable credentials resposne is returned.

can anyone assist? tried every little thing already…
