Biometric Notice issued on March 24, 2023, for April 11, 2023
RFE issued for initial evidence on March 30, 2023, for forms i-684 and i-485. This was my printing mistake. My printer did not print the last line on the form where it says the edition date and the serial number of the form. I was asked to print them again and send them. They did accept the originally submitted form and started processing them. My advice when you are filling out the form is do not just start filling the form online. Download the form on your computer and make sure that you open it using Adobe and fill it up. That way you will not encounter any form fill-up or printing mistakes. I could have avoided this mistake and avoided the RFE all the way.
I uploaded RFE response on USCIS online account the next day and sent the hard copy within 48 hrs.

I find the "Case Tracker" App very useful for a quick update on your status. I also find USCIS online account very useful too for case status and downloading the letters/notices and uploading the response.
