You can currently add an Issue by placing a pin on a 3D element, but the ideal would be to add an Issue by right clicking on the element in the browser of the model or directly selecting the element in the viewer and in the Issue card to show you not only the description and other features but also the photo of the element or 3D scenario. In my browser when I select an Issue that has been created by me or someone else, it does not show where it is pin with the number of issue, I see all issues but not the one that interests me and I do not know if It is a browser error because the mobile looks correctly.
