The day I posted Garmin City Navigator Europe NTU 2024.20 it was with the older version of Garmin Express v7.18.1.0.
As I do not update new maps the day the come out I wait a week or so.
But then there was an update to Garmin Express v7.18.3.0 and after that Europe NTU 2024.20 did not show any more on any of my Garmins to update. It want back to NTU 2024.10. This has happen once before with Garmin.

So we will just have to sit back in wait and see what happens.....
