>I am curious though, how do these scammers keep updating the delivery details on the Ebay site?

They do it by being smarter than the system and relying on your greed. It's their job. Here is what I learned in 20 seconds of searching for "how do ebay scammers manipulate tracking info" :

AI Overview

eBay scammers typically manipulate tracking information by exploiting a system flaw where delivery confirmation often only shows the destination ZIP code rather than the full address. This allows them to provide "proof of delivery" that satisfies automated systems even when the buyer never received the item. 

Common Manipulation Tactics

• The "Same ZIP Code" Scam: Scammers obtain or purchase tracking numbers for packages sent to a different address—but within the same ZIP code as the buyer. Because eBay's system only verifies that a package was "delivered" to that ZIP code, it will often automatically rule in favor of the seller during a dispute.
• Mailing Junk Items: Instead of the actual product, a seller may ship a cheap, lightweight item (like a flyer or a small envelope) to a random business or address in your ZIP code. This generates a real, "delivered" tracking status for the carrier.
• Stolen Tracking Databases: Some scammers use "black market" databases or scrape retail sites for valid tracking numbers that match the buyer's city and delivery timeframe.
• Address Redirection: A scammer might ship a package to a valid address but then use a carrier’s "intercept" or "redirect" service to send it elsewhere, or intentionally provide an incorrect house number so it is delivered to a neighbor or local business.
• "Double Tracking" Distraction: Some sellers provide multiple tracking numbers—one that shows "delivered" (to the wrong address) and another that remains "pending". This confusion stalls the buyer from opening an "Item Not Received" (INR) case, as the system thinks part of the order is still in transit.

 

Let us know what ebay does now that the seller has successfully delivered your new Sigma Pro, and just in the nick of time, too!

Scammed

I would imagine UPS could provide ebay the exact delivery address they used, and if it doesn't match your address on file with ebay, you may have a leg to stand on to refute delivery. Meanwhile this seller has had your $$ for over a month now.
