After linking with SendGrid, URL in e-mail is replaced

When click tracking is enabled in SendGrid settings, the site URL displayed in the invitation email may look like the following.

https://u12345678.ct.sendgrid.net/ls/click?upn=c-2B...
The problem is only with the display, but when you click on it, you can go to the expected page.

To solve this problem, disable click tracking by referring to "4. Disabling Click Tracking" in the SendGrid integration tutorial, and then check the behavior.
