I have similar problem, I got plat status from AA about a month ago and AY still sees me as a Ruby not Sapphire. Called AA about it after and they say it should change automatically. Haven't flown in three weeks but booked flights for next week on Finnair and still its Ruby in their system. Have others had similar problems?
Other data point is that I had to get status updated manually with AA because of their problems with IT systems..
