When I start recording my app, the recorder jumps over the start page when I want to select a country and so on and I have to do it through the mobile device in order to move on. Then I can use the recorder for navigating through my application.
It’s possible that the tests are skipping the start page because the start page is not what Katalon Studio/Appium are expecting for the start of your app. This can happen when your main app includes a third party library for a starting login form, for example.
You may need to set the appWaitActivity and appWaitPackage Desired Capabilities for the test to start correctly.
