Just got an email for my iPhone case is coming. Apple email says no signature required, but UPS My Choice said "The driver may not leave this package without your authorization". Doesn't this cancel out the purpose of no signature? They won't leave the package if I'm at work. So I might as well just sign it, I have to be here. The concern is that I'm not sure if checking that release box also releases all future shipments to the address. I have iPhone 7 package scheduled on Friday. I'd like to have that picked up at the hub. How does this work?
