Great Taste - Horrible Texture

I was delighted when a vegan range came out and I’ve tried all four shakes. The same applies for all of them, unfortunately; really fabulous flavour but horrible gritty texture form the main ingredient - oat flour. Please Exante, do some vegan shakes that aren’t low sugar? There’s a huge vegan community, growing every day. It would be great to have something that’s a pleasure to consume.
