I've been sharing a project via the Enscape web standalone feature with a client who is accessing the link using an HP ultrabook.
The problem they're experiencing is that Enscape is using the device's internal compass/sensors to look around within enscape by default. So physically moving the laptop around moves the enscape view. This makes it very difficult for the user to navigate using the mouse and keyboard because when they try and look around using the mouse, the device sensors compete with the mouse which makes it nearly impossible to navigate. It's almost like Enscape thinks the ultrabook is a VR headset, but I can't find any way to turn this off in the web standalone settings. The ultrabook is not in tablet mode.
