Snyc3 maps update issue

I have never done anything like this in the past.
I am in the UK and have a 2020 focus ST line, i have just updated to the latest sync3 (3.4.23188), file size 3.11G, this completed successfully.

The ford site also say there is a maps update available my current version is F8 so clearly outdated. My issue is when i download it from the ford site (https://www.ford.co.uk/support/sync-maps-updates) the download size is only 49kb so clearly not the correct size.

Is there any way for me to get the latest maps?
