At 6 weeks, exactly, from when DoS received the application, my DW's renewal ticked over to "APPROVED" at https://passportstatus.state.gov/, and https://www.usps.com/manage/informed-delivery.htm now shows "USPS awaiting item from PASSPORT SERVICES/DOS TUCSON, AZ".
We signed up for "Email Updates" at the status site, but no email (yet).
PS: We paid for neither "Expedited Service" nor an Expediter.
PPS: My renewal is still reporting "IN PROGRESS" 😞
