Exporting to Excel a grid and nested grid

Is it possible to export a grid and the nested grid.?
I am using SC9.3 but I can’t find the way to export the nested grid. Only the main grid is exported.
Is it a bug ?

Hi, this feature will be released in the SC9.4 soon.

It’s supposed to be possible, and it used to work, but it seems that last updates crashed that functionality… I’m not able to export nested grids to excel anymore either… help please!
