recently the VR icon that allows you to switch to VR mode on a mobile device has disappeared from the menu when viewing my tour with a chrome browser on android.
it still appears with different browsers and when viewed on the desktop with a computer.
can anyone advise what may have happened and how i might correct this problem please.
even more strangely the menu does appear (using chrome android) with the same tour but when hosted on a different server. the only difference is that the one where the menu button is invisible is launching from a server via an .htaccess file.
any help welcome
