La funcion armonizar no fucinona

Hi @eamarreros make sure you are following these steps:

Desktop instructions:

1. Open the scenery or background image to which you want to add an object in Photoshop (beta).
2. Add the object image to a new layer.
3. If the object image has a background, select Remove background   from the Contextual Task Bar.
4. In the Layers panel, select the pixel layer of the object image.
5. Edit the image to change the size and placement.
6. Select Harmonize from the Contextual Task Bar and choose a suitable variation.
   The object blends seamlessly with the background. The generated results appear in a new layer
