I'd give it another go with any answer you may have tried previously...

I couldn't find an answer that was accepted, despite having the decrypt
for more than a week, so got in touch. They replied "Apologies. We had a
typo in our solution and in the clue. These have now been corrected and
your (correct) answer should now work".

You'll also see on the web page "19th February 2025: Answer corrected".

Not sure how the problem was solved in ten minutes of going live, if they
didn't have the right answer themselves. I guess that was just a fluke.

The clue was just a bit mangled and read "M: Groan. This one is more will
get you in a spin. If you get mixed up. Take a deep breath and count to
three". It has now been corrected to read correctly.

The maths element is more difficult than the cipher - for me anyway.
