ESE is a major PITA.
I know this is off topic but might be useful for some ebay buyers/sellers. Last month I had a two week period where there were no scans on around 20 Standard Envelope shipments. The only way I knew it was delivered is when I got feedback from the buyer. I take video of the the bulk mail drop just in case I get a IND notice from ebay. Not sure if it would suffice for the insurance claim but I have my proof that it shipped.
Also, FWIW in case you never get consistent ESE scans as a shipper. I think I finally figured it out. I bought plain white 4x6 mailers and print my label directly on the envelope at 1200 DPI. I also scale the print to fill the envelope making sure the QR code is no less than 1/2 from the top right corner. I also tape my mylar flip with coin to the right side of my insert (as far right or left as possible). This seems to be working well as I'm at 100% scan rate over the last 4 weeks or so. Prior (with an adhesive label) maybe 1 of 5 would never get scanned.

I swing a metal detector and have a knack for finding dirty old coins.
