they could've left it in the community mailbox or with security but now I have no idea where it is.
went to my usual post office and after lining up for 30 minutes they found the package
looks like there was no attempt to even deliver it to my home as the mini sticker to remove from the package to affix to the pickup notice is still in place on the package
there was no signature required at the post office so they could've just left it with my security to sign for, or the community mailbox, or even in my mailbox, but they chose to redirect it to the post office.
next day edit:
so TODAY the pickup notice card magically appears in my mailbox. so either they put it in the wrong mailbox yesterday and one of my neighbours was smart enough to shove it back through to the other side and the post man put it in my mailbox today, or more likely, they didn't even attempt delivery yesterday and are doing everything backwards by redirecting to post office, then today delivering the pickup notice card.
