Can't see some image in responsive visualization

[Adriano]

Hi, I developed an app for Qlik Sense Server. I put it in QMC. Inside the app there are some extensions to visualize images.
I create a custom CSS to make responsive the app and to have the opportunity to show it with the smartphone by connecting to a specific URL.

The problem is that, if I show the app from a web browser on my pc/laptop, when I resize the screen of the browser, I see all the images, then if I show the app from a web browser on my smartphone I can't see all images.

I tried to debug and I found that the folder "content/default" is not shown when I choose the smartphone view, instead if I visualize the app from my pc the "content/default" folder is shown.

What could be the problem?

Thanks,
Adriano

1) you can use Client Authentication for mobile represent

2) If you are using same app, First option will help but you can use different images which is width, height for mobile / different application
