Submitted renewals for my kids (12 year-old twins) at 2 PM and they were both approved at 2 AM 36 hours later with no interview. They had traveled to over a dozen international countries since they first got their Global Entry including Egypt and Qatar, which are two that I feared could raise the chance of needing an interview.

What is particularly strange though is that I never submitted payment for the renewal, is that typical now for minors or renewals or ???? I couldn't find any mention of this online with a quick Google search.
