Where's My Refund? Says info provided is wrong.

I filed my taxes on Jan 27th when the IRS started accepting e-file returns for 2019 tax year. My wife and I file separately. Both of our returns were accepted at the same time and when I check the refund status on my return, I get the standard display with Refund Received/Approved/Sent. For my wife's return I get the following message, "We cannot provide any information about your refund. You must wait at least 24 hours after you get the acknowledgement e-mail that your tax return was received by the IRS". Anybody know what the difference may be?
