My side business is a transportation management system (TMS) that communicates with shipping carriers. Because I got so frustrated with this exact problem I developed a series of “hacks” so that when this happens customers don’t actually see it marked shipped until someone confirms it.

It’s very annoying but I think it’s worth it to convey accurate information. A lot of misunderstandings and pissed off customers come from shitty tracking APIs. My other favorite is “out for delivery” when it’s not; they don’t want to get in trouble for delivering it late but by lying to people you’ve just pissed them off even more.
