I'm late coming to this one and really struggling to get a foot in the door. I don't understand what it means about five pairs of clues being swapped. Any enlightenment would be gratefully received.
I’m finding this a slog to complete all the clues before progressing to the next stages. I’ve only found a few of the swapped clues so any hints would be appreciated. Also I think 20d is a swap with 17a but I have entry beginning with an L which doesn’t fit with what I think is the location.
