I was looking to add some flavor boosters to my next subscription order and I saw the new Huel Natural Flavor Boosts - Exp, clicked on it and found the added extra flavors like Peanut Butter, Salted Caramel etc. I selected both PB and SC but when I try adding them, I’m getting a “invalid quantity” message, even if I try adding 2 of each, or add another flavor option I still get the message, anyone else having this issue? Are these new flavors not available yet and that’s why I’m getting the message? Would love to try these new flavors.
