Please can someone help . When I try to sign into facebook it tells me to please confirm a security check and that a confirmation code has been sent to my mobile phone, I never recieved it, even though the number is written correctly. When I click on ”resend” it displays ”You are trying too often. Please try again later.” even though I leave hours between trying.
