Just an FYI incase you are on the same boat.
Through the chat with USCIS online agent, currently USCIS is behind updating many online case status. In my mom's case, it still read her I485 was denied even we got approve letter of I290B. The agent confirmed dont need to pay much attention to online case status now, the case is re-opened and in good status.
I did ask how long the processing time is, the agent didn;t answer directly but informed the case is really good condition, and is being processed now, we just need to be patient till the decision is made through mail.
If anyone could share your recent I485 case processing time would be very helpful.
