Not able to run multiple appium apps(in parallel)

I am trying to write end to end test using two apps and one browser. Currently my code works with 1 app and 1 browser. However when i try to add two apps with one browser it is not able anything after setting up the environment for 2 apps and the browser i.e it opens both apps in a simulator and it opens the browser.

Here is my code:

wdio.ios.app.conf.js

    require('@babel/register')

exports.config = {
    runner: 'local',
    //
    specs: [
        './tests/specs/**/*.spec.js'
    ],
    //
    exclude: [
        // 'path/to/excluded/files'
    ],
    //
    //
    baseUrl: 'http://localhost:9174/',

    capabilities: {
        chromeBrowser: {
            capabilities: {
                browserName: 'chrome'
            }
        },
        shopfloorApp: {
            port: 4723,
            capabilities: {
                platformName: 'iOS',
                'appium:deviceName': 'iPhone 8',
                'appium:platformVersion': '12.4',
                'appium:orientation': 'PORTRAIT',
                'appium:noReset': true,
                'appium:newCommandTimeout': 240,
                "appium:platformName": "iOS",
                "appium:deviceName": "iPhone 8",
                "appium:bundleId": "com.farfetch.sof.shopfloor.chanel.debug",
            }
        },
        consumerApp: {
            port: 4724,
            capabilities: {
                platformName: 'iOS',
                'appium:deviceName': 'iPhone 8',
                'appium:platformVersion': '13.2',
                'appium:orientation': 'PORTRAIT',
                'appium:noReset': true,
                'appium:newCommandTimeout': 240,
                "appium:platformName": "iOS",
                "appium:deviceName": "iPhone 8",
                "appium:bundleId": "com.farfetch.sof.consumerapp.chanel.debug",
            }
        }
    },

    services: ['appium'],
    /* appium: {

        args: {
            address: '127.0.0.1',
        }
    }, */

    //
    //logLevel: 'trace',
    //
    //deprecationWarnings: true,
    //
    //bail: 0,
    //
    waitforTimeout: 20000,

    jasmineNodeOpts:

    defaultTimeoutInterval: 60000,
    expectationResultHandler(passed, assertion) 
    {
      // do something
    },
}
    //
    //
}

here is my testfile:

```
import ClientScreen from '../screenobjects/client.screen';
import SearchScreen from '../screenobjects/search.screen';
import HomeScreen from '../screenobjects/home.screen';
import FormScreen from '../screenobjects/forms.screen';
import CommonPage from '../pageobjects/common.page';

describe('Sending the item to the mirror successfully,', () => {

beforeEach(() => {
    CommonPage.login()
});
/* afterEach(() => {
CommonPage.logout()
}); */

it('should be able to send the item to the mirror', () => {
    shopfloorApp.$(ClientScreen.clientTab).click();
    shopfloorApp.$(ClientScreen.searchButon).click();
    shopfloorApp.$(ClientScreen.searchButon).setValue('[email protected]')
    CommonPage.hideKeyboard()
    shopfloorApp.$(ClientScreen.customerlabelButton).click();
    driver.pause(5000)

    if (shopfloorApp.$(ClientScreen.assignmentButton).getText() == 'Assign to me'){
        shopfloorApp.$(ClientScreen.assignmentButton).click();
    };

    driver.pause(8000)
    shopfloorApp.$(ClientScreen.fittingRoomButton).touchAction('press')
    shopfloorApp.$(ClientScreen.mirrorName).click();
    shopfloorApp.$(ClientScreen.assignMirrorButton).click();
    shopfloorApp.$(HomeScreen.productsearchButton).click();
    driver.pause(3000)
    shopfloorApp.$(SearchScreen.handbags).click();
    driver.pause(3000)
    shopfloorApp.$(SearchScreen.viewAll).click();
    shopfloorApp.$(SearchScreen.actionListButton).click();
    //chromeBrowser.url('http://localhost:9174/')
    //shopfloorApp.$(FormScreen.alert).pressButton('Send to mirror');

});
});
```

Note that if i remove the consumerapp from the config file and stay with one app and one browser, it works great.
