However, when I launch the app, no website content loads. I would expect some problems with CSS or JS rendering, but at least the raw HTML should be loaded.
We just see a blank screen, no matter if the package is built with Advanced Installer or the MSIX Packaging Tool. (I attached a test package built with Advanced Installer, first unzip it, don't just change the extension).
Are we doing something wrong? Or missing something else?
A customer sent us a similar package and we are trying to figure out what is the problem.
We know of a previous problem where local HTML files from the install folder of the msix/appx package were not loaded because of their encoding (if I remember right UTF-8 was required for the files to render correctly). Is this the same problem here? or something related to it.
When the app runs natively, does the app load in a window controlled by the app or by a browser window. If it is a browser window, is it a specific browser window (i.e. IE) or is whatever the default browser is?
