Vba Worksheet_Change event does not trigger when copy and paste data into column but works with a manual click into cell - excel

Question

I am trying to solve an issue with a piece of code. I am aware this question has been asked before but i cannot get those solutions to work. The below worksheet change event does not trigger when i copy and paste data into column A but does when the user clicks into the cells manually how can i get round this?
Private Sub Worksheet_Change(ByVal Target As Range)
Dim cell As Range
 
   Application.EnableEvents = False
 
For Each cell In Target
If Not Application.Intersect(cell, Range("A7:A1048576")) Is Nothing Then
If Not IsNumeric(cell.Value) Then
    cell.Value = vbNullString
    MsgBox ("Please re-enter, value entered contains non-numeric entry")
End If
End If
Next cell
 
If Not Intersect(Target, Range("A7:A1048576")) Is Nothing Then
On Error Resume Next
If Target.Value = "" Or Target.Value = "0" Then
Target.Offset(0, 12) = ""
Target.Offset(0, 13) = ""
Else
Target.Offset(0, 12).Value = Format(Now, "mm/dd/yyyy HH:mm:ss")
Target.Offset(0, 13).Value = Environ("username")
 
End If
End If
    Application.EnableEvents = True
End Sub

This code should just about do what you want. Please try it.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim Cell As Range
If Not Application.Intersect(Target, Range("A7:A1048576")) Is Nothing Then
Set Target = Target.Columns(1) ' remove all cells outside column A
Application.EnableEvents = False
For Each Cell In Target.Cells
With Cell
If .Value = "" Or .Value = 0 Then
.Offset(0, 12).Resize(1, 2).Value = vbNullString
Else
If Not IsNumeric(.Value) Then
.Value = vbNullString
MsgBox ("Please re-enter, value entered contains non-numeric entry")
.Select
Exit For
Else
.Offset(0, 12).Value = Format(Now, "mm/dd/yyyy HH:mm:ss")
.Offset(0, 13).Value = Environ("username")
End If
End If
End With
Next Cell
Application.EnableEvents = True
End If
End Sub
