Unable to select seats via AA site on OWE

[bertflyer]

Hi all,
I am starting a OWE in Y next week and have been able to select my seats on the QF and BA legs of the trip online. However, I am unable to do so for my AA flights using their US site which in the past I have been able to do by logging in on the US AA site using my name & booking ref number:

"We are experiencing technical difficulties and are unable to display your reservation at this time. Please try again"

Does that mean I'll only be able to chose seats once I'm at the airport using the kiosk?
In the past my AA boarding passes have shown the priority boarding, should that still show on the BP (I'm SG)?
Hope that all makes sense.
cheers
Bert

Do you have the AA SABRE booking reference?

Thanks Serfty, found that on the itinerary and was able to log in and select seats.
Managed to snag an exit row seat on the B762 from SFO to JFK too!
cheers
Bert
