It should be up already; I've emailed the crossword editor to ask what's going on. My guess is that something's gone wrong given all the production staff are working from home, rather than on their work systems.
I'm going to be very careful about what I say or don't say about this puzzle, because I don't want to give the game away or be accused of giving hints, but I will say that I have proofread the PDF and am happy with what's been published.
