What obvious next step clue I am missing, unless it is an extreme puzzle?

It’s a sudoku-x, so you can’t have a 9 in the bottom left 3x3 in the diagonal since it’s already in that diagonal.

yes, you are right.

Having followed entire X logic correctly to reach this step, I lost track.

This learning is very precious.
