Help needed with London Metropolitan archives offer

[Lynn the Forest Fan]

The latest Lost cousins newsletter advertised this:-
Free access to London parish records 18TH-31ST MAY

The London Metropolitan Archives have arranged for their records at Ancestry.co.uk to be free during Family History Fortnight, which runs from Monday 18th May to Sunday 31st May.

However, whenever I try and view any of the records it takes me to the subscription page. I have found a few things that might be interesting, so it is infuriating not to be able to view them.

Has anyone else had this problem?

Thanks
