Export imagery to KMZ

Hi there,
I have imported a standard S2 tile for the same location on 2 different dates, calculted the NDVI for both and then calculated the difference between the two as a new product.
I am trying to export out the band maths image as a KMZ but I am getting the error message ‘Product needs to be in lat/long’. I read the comments about th need to reproject which I have done but I am still getting the same error message when I try and export the reprojected image in this format.

The original imagery is in Geographic lat/long (WGS84) as the new generated products so I am wondering what I am doing wrong here.

Any help much appreciated. Thanks
Liz

Can you please show a screenshot of the GeoCoding of the product?
First select the product then open this button grafik

And maybe also this one? grafik
