I got the same thing. Applied on 23rd jan 2023. Got receipt notice right away. Then, two days in a row(24th and today 25th) I receive emails from uscis about some action taken. But, I m sure its not approval(not without interview and when its not even 3 year completion of my green card as I applied 90 days earlier). Its just when they are doing something on the file at the back end of the system.
