I am following a tutorial for isometric design. (https://www.youtube.com/watch?v=eFHxknDs4Mk&t=208s)
My problem is when I finished the first path as in the tutorial I can not start a new one which continues the old one.
It shows me "delete anchor point" even I set normal pen tool. And when I set the "add anchor point tool" it shows me "Please use the add anchor point tool on segment of a path".
I will post here the screenshot for better understanding.
