Yeah... there's definitely a problem with your shipper's notifications.
The email that I originally got with my order says to follow the link to "View your order" which takes you to a link to download the "Shop" app for tracking.
Currently your website shows "Your order is confirmed - We’ve accepted your order, and we’re getting it ready. Come back to this page for updates on your shipment status" and the shop app showed only that I had a hub on order (my email address was confirmed through the shop app, and I got that email for confirmation)
Two days ago the "Shop" app changed to show that the hub had been shipped (but no emails or app notifications). And that afternoon, I pulled the hub out of my mailbox, and have it sitting on my desk right in front of me. The Shop app still shows (right now) that it has been "Shipped."
There are no further emails from Hubitat, Shippo or Shop in my email other than the original "order confirmed" email from Hubitat and the email confirmation request from the Shop app to confirm that my email was actually my email -- and I checked my spam folder too...
Super happy that it got here so fast, though!
