As the topic title suggests, touch screen rotation/panning of Sketchfab models no longer works in google chrome. I am not sure how long this has been happening as I haven’t loaded a model on my touch device (surface pro 3 win10 latest build) for a while, but after a bit of a hunt around, it seems that the onTouch APIs have been disabled by default since Chrome version 70.

I know this isn’t a fault of Sketchfab, but any advice on how to rectify the issue would be appreciated. Many websites appear to be affected by this (including earth.nullschool.net), but in others still respond to touch screen (e.g. google maps). Some searching reveals there is a manual fix for it, but there are no clear instructions on how to do it:
