The connections are very intuitive once you learn how to do them. Here are some instructions to help you make connections:
-Make sure the shape recognition is ON
-Make sure you are drawing a straight line not curved or angular.
-Make sure the line is starting and then ending inside the path of closed shapes.
This are the only rules you have to follow, no there are no problems with the connection or at least not that we know of. So it should work like a charm. Watch this video tutorial on connections if you haven’t already.
