Mailed filling to Online Status in MyUSCIS Inquiry

Hi,

Me (beneficiary) and my spouse (petitionary) submit my AOS application through mail and recently received a text message that it was received. For more context, our package was sent to the PO Box in Elgin, IL

I was wondering how long does it take for these fillings to show up in my MyUSCIS account.

Thank you in advance for the help
