Hey @danielpox, the implementation of 3D Touch in Safari 10 changed from iOS9 so by default it does not work. I am currently working on a new version of pressure that supports iOS 10. It should be hopefully released soon.
@albinekb haven't seen anything about it on Chrome on macOS. I hope that the pointer event spec would be adopted by Chrome then the pressure value could be retrieved. https://www.w3.org/TR/pointerevents/ On iOS at least Chrome finally switched to WKWebView so at least that is supported on iOS now.
