[🐛] After logging out or reinstalling the app, the authorized user remains.(In iPhone 7)

Issue

I am implementing a Firebase auth module to enable phone verification in my application. I configure everything according to the documents and everything works (I get SMS). After updating to version 10.1.0 everything works fine on android and ios but when i try to check the code on iPhone 7 it finds the previous authorized user and does not let login the new user.
I don’t get any error other than invalid code.

SMS verification function:

  const clickCheckCode = async () => {
    setLoading(true);
    try {
      /** Validate code */
      setConfBtnIsDis(true);

      /** if (!isUserAuth) */
      let currentUserAuth = auth().currentUser;

      console.log(currentUserAuth);

      if (currentUserAuth === null) await confirm.confirm(value)
      else return;

      /** Get user by request */
      getUserTokenByPhone(userPhone, userCountry);

      setLoading(false);
    } catch (error) {
      Alert.alert('Error', 'Invalid code!', [{text: 'OK'}], {cancelable: true});
      setLoading(false);
    }
};

console.log(currentUserAuth) output:

Try putting this on your AppDelegate.m:

  NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if (![defaults boolForKey:@"notFirstRun"]) {
        [defaults setBool:YES forKey:@"notFirstRun"];
        [defaults synchronize];
        [[FIRAuth auth] signOut:NULL];
   }

put it after

  if ([FIRApp defaultApp] == nil) {
    [FIRApp configure];
  }
