Hello,
I have witnessed a changed in behavior between v4.29 and v4.30, if I try to draw a Polygon in 4.29, if there is only 2 vertices it draws a line between the 2 points.
In v4.30, it draws a point at equidistant from the 2 points.
You can test it here in 4.29, if you change the api to 4.30 you will see the difference

I can fix that by drawing a polyline instead of a polygon when there are 2 vertices but I would prefer just using polygon.
What do you think?
