The USPS has really gone to hell in a hand basket. As a retired electronic technician from the PO I know that Covid and the PM General's policies have really crippled the mail processing network. Letter mail is at historic low volumes and will remain so. It is really sad to see a quasi governmental agency that previously had some of the best numbers for customer satisfaction go down this path.
For some interesting information about the Richmand, VA process and distribution center look here https://www.uspsoig.gov/document/late-and-extra-trips-richmond-va-processing-and-distribution-center . It is not Taylor's fault for the delays.
