Atlanta area has been a disaster for about 2 weeks or so @eyeofthebeholderantiques . This is Missouri City, TX (Houston) round 2. This will be happening all across the country state-by-state as USPS implements DeJoy's inefficient plans to change and consolidate sorting facilities, not only creating massive delays at time of changeover, but adding delivery time overall once things eventually settle down.
My suggestion is to get your carrier or local PO clerk or self service kiosk to scan a bulk SCAN sheet so you at minimum get a provisional acceptance scan and not affect your eBay on-time shipping metrics. (Edit to add: I realize this will not work for eBay Standard Envelope shipments.) Communicate with your buyers that there will be delays and eBay's estimated delivery dates are not accurate.
I suggest filing USPS insurance claims on lost packages as soon as the timeline allows.
If your Top Rated Seller status is affected, or if you end up with very high item not received service metrics, contact eBay customer service and ask them to evaluate your account. With the TX debacle eBay CS applied seller protections on a case-by-case basis, so I expect that will continue with the GA issues, and other affected states. This is the type of situation where I'd avoid the CS overseas chat and instead send a DM to one of eBay's social CS teams if your account is impacted: ebayforbusiness on facebook, ebayforsellers on insta, askebay on X
