SCAN sheets

So if you've supported me in the past, you may have experienced this, and if this is your first order, thank you!
I bring every order to the post office myself, on the very next postal business day and, to save time at the counter, I use SCAN sheets.
Let me apologize, I'm sorry, I don't know why it does this, but every so often they don't update the package tracking info until it's almost out for delivery.  In fact, I've tracked hundreds of other supporter's packages who've reached out to me with emails/chat/DMs that were scanned at drop-off like this:

Shipment Received, Package Acceptance Pending


and not again until they show up at the destination post office and are delivered that same day. 
It's becoming more and more "normal" unfortunately. 
Thank you for your support and patience,
