Normally, the status would mean exactly what it says, but I'm not so sure right now. Try doing a web search with the phrase "Held at Post Office, At Customer Request" and check out a few of the news articles.
"U.S. Postal Service customers across the country have been receiving a notification that often alarms and perplexes them: The message says packages they expected delivered to their home or business are being held at a post office “at the request of the customer.” But customers who are receiving these notifications never requested that their mail be held.
The packages are delayed because of broad changes Postmaster General Louis DeJoy has implemented to the nation’s mail delivery operations, including policies that slow down package delivery.
When a mail carrier cannot deliver a package on the day it was scheduled because their shift is ending, postal workers say, the system sometimes generates a misleading “held at the request of the customer” message."
