When I’m trying to login to my Facebook account it is showing that your account has been locked. I try to unlock my Facebook account and it has sent a activation code to my Gmail account.
But when I open my Gmail account there is no activation code from Facebook to unlock it.
Why is this happening how can I get back my Facebook account?
If your Facebook account has been locked and there is a Gmail activation code sent to your account. It would probably went to the spam folder or the updates, social, promotion folder.
As you stated that your can’t find the Facebook activation code on your gmail account. I assume that you are looking for the code on the primary tab.
Instant please do check social tab, updates tab, promotion tab and even spam folder in Gmail app as shown in the below image.
