Did you make all DOM elements have a transparent background?

Same here, iOS and browser works

alysterlendira commented 1 year ago

the development team should add a css class when running the scan to add a z-index. works fine in browser

The browser implementation is (very) different from the mobile devices so it's not a good comparision. On mobile the camera preview is behind the webview so make sure that all dom elements have transparent background, including html and body. Use chrome or safari inspector to connect to the device and traverse the dom tree.

Just added html, body { background-color: transparent !important; } and it works.
