Rotation of image on tablet

Hi everyone,

I've created a dial interaction, which is to rotate an image so the learner can see it from different angles. It rotates well with fingers turning it on my ipad in html5 (Safari and Chrome browsers) and the storyline app of course.

However, in html 5 on my touchscreen laptop, the rotation is not working at all by using fingers, in tablet mode in Chrome, Edge or Opera -- mouse/cursor is working fine as normal. Has anyone else had this issue, and/or resolved it?

Thanks,

David
