There is a bug for the Craft Prototype function.
In a sketch, the link works well in a preview.
However, the click mark(blue box) is often not displayed on the Invision Web. It doesn't show at all.
So if you upload it again, it will be displayed. But the click marks that I just saw is gone. I think it's a bug.
There are times when I succeed in seeing all the click marks if I continue to upload a few times, but this is a tiring job.
I think it's a bug related to the one I inquired about earlier.
