If you are installing Waze on a second device, and email is received on primary device, you CANNOT click the Verify email button on Primary. You must receive and open the verification email on the same device on which you are trying to install, else you receive the bogus error, "Can't verify email" on the primary device. This is a design flaw that should be fixed.

Until then, this odd requirement should be made clear to the installer in the Verify email - that it tell the person installing/opening the email that the email must be accessed from the same device where the installation is occuring.
