it should be under the teas option and I believe that button is either yellow or green. I believe the option for lattes is the same. you’d just choose the milk itself not with milk. so it will charge the person for the milk. but don’t quote me on the latte part. i’ve just never seen an option for a custom latte unless it’s just a regular latte with add ons. if you wanted to do like milk with another syrup and such, you can go to other and click cold milk and then do adds ons. something along those lines. it’s probably whichever option costs more
