What was confusing is the shipping label Google provides is a USPS label. The instructions are to take the package to the post office or (confusingly) to a FedEx shipping location. Now why would I take it to FedEx if the label is for the Postal Service????That sucks. I know when it comes the other way Fedex to USPS (smartpost) it is still trackable. But I agree, when returning something like a phone you sure do want to get a notice that it was actually delivered to the company. When I returned my S20 a few years ago, Samsung did give me some problems on the return; however, the information that it was received by Samsung, ended that debate.
Now I know.
It is still trackable but with FedEx.
