Hello everyone，I'm doing some exercises about how to route diffenertial pair. I have set up the matched lengths rules(as Robert teachs in Advanced PCB Layout Lesson 4),but the tracks didn't nice.Below are screenshot of my PCB and the iMX6 Rex Module

Hey,
You'll have to play around it.
You can drag it make it look better.
PS: I see that trace width are different have you followed Layer stack up for the impedance?

as @Lakshmi said, the track shape was manually adjusted.
