Strangely, my latest attempt at a WebVR tour has a Wakelock problem. The phone falls asleep after two minutes without a physical touch. Two minutes being the Auto-lock time on my iPhone. This doesn't happen with other tours in VR mode. The main addition for this tour is two sound tracks, voice over plus music. Also a thumbnail menu. Can't imagine either being the cause.
iOS 10.0.2, KRPano 1.19pr6, iPhone 6s
Before spending a few hours running this down are there known situations that could cause this?
Here is the site (work in progress).
Thanks
