I have the same thing going on. I placed an order on 2/18/22 and it also shipped on February 20 with an estimated delivery date of 2/24. When I go to try the order, no tracking information comes up and the message that pops up onscreen says to check back later. When I enter the Tracking # at USPS, there is also no info.
I will give it another week and if I don't receive my package or no information is available, I will send an email to the QVC Social Team. They are always so wonderful and helpful. I think we just have to give it time to see what happens.
