I received my passport a few months ago and have been trying to update my info on the Global Entry website. After attempting this several times, I get a cannot validate window and to check my entries. I sent in several forms in the FAQ section with no response on how to update the information and link the two document numbers.
I called Friday and actually talked to a real person in a reasonable amount of time on line. They said this is a known problem and I have two options. If I am in a hurry go to a registration/interview site and have this corrected or if not in a hurry, check back in a few weeks. I guess their system is backed up.
The saga continues.
