I earned Premier (2P) status on my out bound flight, a day later the status was active on the united.com website, but the next day when I checked in (OLCI) for my return flight, the status is NOT noted on the boarding passes in any way.

I'm currently in E+ on a trans-pacific, and I am in seating category 4, I had thought that 2P status gave you access to seating group 1. Can somone clarify this for me?

Any ideas on why the status is not reflect on the boarding pass? Is there anything I can do to get it updated? I'm also waitlisted for an upgrade on the trans-pacific leg, so I want to make sure I'm not lower on the waitlist then I should since the 2P status not listed on the departure management card either.
