C4 GP 2017 Update not downloading

[GoOnYahGoodThing]

Hello,
Could I please ask for some help.

Went to the main dealer here to get updates for the car.
The guy there gave me a link to download the Citroen Update software.
I did that and entered my VIN.
It went to the download screen and it lists two downloads.
I am able to get the map update no problem.
But then it keeps failing to download "Software of the touch screen (21.08.87.32_NAC-r1)"
And the Continue button is greyed out.

Im not sure what to do next. I've tried that download a few times with the same result.

Thanks in advance for any help.

The car is a 2017 Flair model. It does have wifi.

If all else is working I wouldn't worry about it - updating the firm ware risks something else stopping working!

The maps are badly out of date and the android auto does not work properly.
So I really do need to update this stuff.
Thanks
