How long does it take for the info on the prefund.aa.com page to update?

I had an AA codeshare flight operated by AS that had a significant schedule change. My flight number disappeared and I was booked onto a codeshare that departed 3:50 earlier, even though AS had a flight that departed 30 mins after my original flight time. As it wasn’t offered as a codeshare, my only other alternative was a flight that departed 4:15 after my original flight, or AA offered to change my route to SAN-LAX-SEA purely on AA that would have doubled my travel time, so I opted for the refund route. The phone agent was able to cancel my flight as it no longer showed up under my trips after the schedule change (I only noticed when I got a flight change notification from the AS app) and they advised me to submit the refund request online.

It’s now 24hrs later and if I do a search on either ticket (my wife was flying with me) I get a refund request not found message.
