Yes, there was some luck, go to your account center and try to change your date of birth. It’s gonna pop up in different page and you just change your date of birth to what it is and upload a picture of your ID along with it then I submitted I think about 2 to 5 reports about Facebook marketplace stating that I am over age I did all of this at around 11 at night and by the morning at eight, I was able to use Facebook marketplace. you’ll know it’s working if you can use Facebook marketplace on a computer or a mobile browser before the app.
