Why a delay on the tracking? I never get that issue with ups always FedEx. Sometimes it takes a couple days to get a update .

I don't usually have that issue. You should ask FedEx directly about this problem.

What devision of FedEx are you having a issue with tracking a package with? Are you noticing this on p.c. and mobile phones? Make sure you get a confirmation and all billing information filled out and confirmed with any 3rd parties. If all is good. Call customer service number
