I am using Windows 10 Enterprise 64 bit, Office 2016 Pro 64 bit. I am trying to copy 2 shapes from one worksheet to another worksheet.
The following API code works sometimes, but most times it shoots an Error 1004 for Copy or Paste (Clipboard timing issue). I have tried using different solutions e.g. Timer, Wait, API etc., but seem slow and buggy most of the times! Also i am trying to paste the images on opposite ends of each merged cell. I have also attached a sample file for inspection.
I don't remember but i read somewhere that if i create separate copy and paste functions/procedures, then it might solve the issue, though not sure!

EDIT:
@iinspectable, it is not a normal Copy-Paste issue, but a clipboard timing issue if copy paste is involved in a loop i.e. copy paste done multiple times. Here's an example where the SingleCopyPaste procedure works, but not the MultipleCopyPaste procedure. I hope you get my point now.
Option Explicit
Sub MultipleCopyPaste()
    Dim shp As Shape
   For Each shp In Sheet1.Shapes
      shp.CopyPicture
      Sheet2.Paste Sheet2.Range(shp.TopLeftCell.Address)
    Next shp
End Sub
Sub SingleCopyPaste()
    Dim shp As Shape
    Set shp = Sheet1.Shapes("Arrow")
    shp.CopyPicture
   Sheet2.Paste Sheet2.Range(shp.TopLeftCell.Address)
End Sub
