Sorry we missed this @BeACat, thanks for the nudge!
As Phil has said to meet Japanese regulations we’ve had to make some tweaks to the formula, as a side effect the fibre has decreased. In future we may be able to offer a higher fibre version, but it’s a wait-and-see.
We’d love to! For now we want to really focus on delivering the best quality customer experience we can at the best value possible. To do this we’ve got a more limited range than in the UK, but as you’ve probably seen we don’t stand still so it won’t always be like that.
