Hello all,

I am doing a simple app that is doing barcode scanning.  
I am using the block camera.  
It is working well with le live test but it is not working after publishing the app in webapp.

Thanks for your help  
Alex

Can you be more specific? What is/is not working in the web app?

When I am clicking on the button the camera does not open

I tried on Ios and on android and both are not working ☹
