I think I am misconfiguring materials or packaging to html5 to work on mobile devices. Because it works perfectly in the ue4 editor, on the desktop but always gives an error in the mobile search engine. As much as it simplifies the application.
This the error in mobile and you can try [here][1]
I have compressed the project in case it can be checked if it is an error or a bad configuration.
