I suspect Swarbs is referring to the comments under the puzzle on the Guardian site, Norah.
There’s been a software change. I can see the comments but note that others are complaining about it.
The comments section for this crossword do not appear at the bottom of the page. I found them by clicking at the top. This change seems to be one of the improvements made in the latest update.
From the ever growing list of comments, Guardian folks really don’t like the changes. It’s nearly as bad as the recent meltdown at 225 following the introduction of avatars!
