Manifest scans continue to cause lack of tracking updates

Anyone know who I could contact at USPS to work on the issue where tracking updates don't populate if a manifest barcode is used?

Each week I drop off 50+ packages at my post office....I unload them myself and put them in the carts, then give the manifest to the team there. Unfortunately the only update to tracking is "Shipment received, package acceptance pending" until the receiving post office gets it - no hops, no other updates.

This has been going on for months. I hate to tell my local post office folks that they need to scan every package, but I'm at a point where customers are getting upset at me - especially when there's a weather delay like this past week.

If someone from USPS IT is here and wants to DM me, I can reproduce the issue, explain the steps I take, etc.

Maybe I should contact someone from Consumer Affairs, anyone know how to get in contact w/ the right person there? I'm in central MO.
