As this question points out hitting cmd+shift+H twice or hitting the home button twice should open the app carousel and swiping up should close an app.
Yet I found myself pressing it multiple times and the carousel only shows up about half of the times. Other times 5 consecutive presses brings it up. Sometimes it just goes to the home screen and only works if I go inside the app again and do it from there. I wonder, is there a reliable way to go about it except resorting to this voodoo? ;-)
I am working with react-native storybook if it holds any significance:
npm run storybook
I am working on iPhone 6 plus simulator so the iPhone X simulator swipe up is less of an option for me.
