I'm using a JS library (Pannellum) that enables use of the motion sensors available in Apple devices, but when I view my site on a large iPad (12.9-inch) it defaults to the desktop site and makes the library think the sensors aren't available. If you 'Request mobile site' in Safari's settings then it will work, but I'm trying to work out how to make it load the mobile site by default. FWIW I don't have a separate mobile endpoint, it's just a static site using Bootstrap to determine CSS changes at various breakpoints. I'm sure the solution will likely be some missing value in the tag, but I haven't been able to find out what, most existing questions of this nature seem to ask how to do the opposite (force desktop view). Would appreciate it if anyone could point me in the right direction!
