Broken in in safari in iOS 12.2

Safari no longer allows access to direction and motion sensors by default from iOS 12.2. The only way to fix this seems to be to have the visitor manually allow access to these sensors in Settings > Safari > Motion & Orientation Access. There is still an chance that in a future iOS version access to Motion and Orientation can be requested the same way now access to location is already managed, but for now we will have to advise visitors to manually enable this access again.
