In-app Browser opens blank video after entering website in iOS


A website that I’m working for currently has issues when accessing via the in-app browser on iOS. When a link to it is opened in KakaoTalk, it opens a blank video page and stops rendering the page properly. This behavior is not the same on Safari or on Android, whether that’s on native app or the web browsers. You can see this behavior in this example video

Could you help me in understanding this issue and see what are the steps to take to make this work on iOS?
Best regards,


Can you tell me the URL that can be reproduced?

Hi there,

yes, you can test this with the following URL:

This code executes the video.
Please provide a plain text of the code. I will deliver it to the person in charge of Kakao Talk’s in-app browser.
