I've had similar problems to those discussed. To try to circumvent it all, I thought I would order a will to see if, when it was ready, they would email me with a link that actually worked.
Still more frustration though - the will I wanted had no Folio number, but the order form would not function without one - it just said 'Folio number required'.
I hope the amount being paid for this update will be reduced to take account of the mess being made of it!
