Device orientation / motion permission activation

We have a web-based viewer which makes use of device orientation.

The permission box only appears on a “touch” and not on a swipe or pinch. Is this normal?

We’ve already tried different listeners: start, end etc but it’s still only initiated the permission request upon a physical touch / tap on screen.

Any ideas / suggestions would be gratefully received.

Many thanks in advance.
