1. I created QR code that will open my website. the website is dynamic link to go to line app or websit. 2. I scan QR code with LINE QR Scaner and then the websit open after that it will redirect to open LIFF 3. Sometimes around 40%, LIFF doesn't display anything and you cannot click all button in LINE app but if you click a position that is button in LIFF, it will work even if you doesn't see anythings. if you need to exit, you have to use back button or clear LINE app. if you use back button, it will close LIFF. you will see your LIFF is closing.
