On the tour setup page, under General Settings and you will find the field “Gyroscope Control”. Turn it “On” to activate it on mobile devices.
Once you publish a tour, embed it on the page or post you desire.
Opening that page/post of a mobile device will show a small icon on the top left corner, just below the control menu. Tap on it to activate it and tap again to deactivate the mode.
