im using firebase auth sendSignInLinkToEmail() with universal links, not dynamic links. When i get an email, i click the email sign in link on my iPhone, but it opens my website, instead of opening my iOS App.

the links looks like ://mydomain.firebaseapp/__/auth/action?apiKey%3DAIza...C8_X8%26mode%3DsignIn%26oobCode%3DQC...FzuA%26continueUrl%3D

mydomain and myteamid are replaced accordingly.

why is the link not deep linking and opening my iOS app?

Setup

1. "react-native: "0.73.0"

2. firebase,

   • Email link (passwordless sign-in Enabled.
   • added authorized domains: mydomain
   • ios settings > team id = myteamid

3. react-native code

    const actionCodeSettings = {
       url: '',
       handleCodeInApp: true,
       iOS: {
         bundleId: 'com.mydomain.main'
       },
       android: {
         packageName: 'com.mydomain.main',
         installApp: true,
         minimumVersion: '1'
       },
       linkDomain: 'app.mydomain'
     }
     await sendSignInLinkToEmail(auth, email, actionCodeSettings)
   

4. Appdelegate.mm, followed: Universal Deep Linking in react native 0.73

5. myapp.entitlements

     <key>com.apple.developer.associated-domains</key>
     <array> <string>applinks:app.mydomain</string></array>
   

6. following:

   5.1. apple-app-site-association verified app.mydomain using /

   {
   "applinks": {
       "apps": [],
       "details": [
           {
               "appID": "myteamid.mydomain.main",
               "paths": [
                   "NOT /__/auth/action/",
                   "NOT /__/auth/handler/",
                   "NOT /_/*",
                   "/*"
               ]
           }
       ]
     }
   }
   

   5.2. Configure your project to use the new links. ran the script, Response 200 and

     ProjectConfig {
       smsRegionConfig: {},
       multiFactorConfig_: MultiFactorAuthConfig {
         state: 'DISABLED',
         factorIds: [],
         providerConfigs: []
       },
       mobileLinksConfig: { domain: 'HOSTING_DOMAIN' }
     }
