Data Point
2025-06-25 - mid-day East Coast (USA) time - applied for renewal for my mid-teens son's GE.
For my son's previous renewal, I vaguely recalled I had to take him to the airport for an "interview" at which the officer sort of sighed and said something along the lines of "I don't understand why they called for an interview for the kid" and went through the motions of checking the kid's passport, etc.
Was not encouraging to see "Appointment" as part of the process on the confirmation screen after this most recent renewal. But, I suppose that's standard language on the status screen because...

2025-06-26 - late evening East Coast (USA) time - application approved. The "Appointment" / "Interview" requirement was now bubbled in in green color and all that we needed to do was wait for card to activate it.

2025-07-05 - Global Entry card received via USPS first class mail at mid-Atlantic residential address near Washington, D.C. Still has photo of now-mid-teen son as a toddler when we his photo was taken at initial appointment 10+ years ago.
