Sometimes you run into issues with your cordova builds of your project. Inspecting them is easier than you might think for Android you can use chrome://inspect/#devices in the chrome browser to inspect devices or emulators running your app.
For iOS you can use safari web inspect in the debug menu. Note though you must enable the web inspector in the device/emulator you want to inspect. You can do this by going to “Settings > Safari > Advanced” and turn on “Web Inspector”.
