As said above, just wait out the hold. It's usually 30 days for new sellers.
eBay Standard Envelope (ESE) is a metered mail shipment so it does not receive traditional tracking scans and the clerk at the PO counter cannot scan it. The envelopes are scanned by sorting machinery at distribution centers along the way.
Common reasons ESE envelopes don't get scans include:
- Overpacking. Envelopes are too stiff. It's not recommended to use trading card top loaders or cardboard mailers.
- Using ineligible packing material such as a bubble envelope.
- Placement of label. Label should be placed in the upper right corner with approx 1/8"-1/4" clearance from edges. If it's placed too far from the corner the machinery won't scan it.
- Placing items like coins in the center of the envelope. The center of the envelope needs to be the most flexible part.
- Printer ink is not dark enough, or label color is too bright (stick to white labels if you can).
- Regional issues with sorting machines, volume processing, etc.
With ESE, a 'delivered' scan generally occurs at the last sort facility before it gets to the buyer, so typically the buyer will receive their order a few days after the delivered scan.
