Different Prices to Different Customer - Portion Issue

Hello Sir, I have an issue with Price Definitions, When I used New Portion it doesn’t work

Changed your post from Tutorial category to V5 question.

you cant set price definitions per portion, you can only have price definitions for the main product price

Pretty sure you can, price definitions are on price list editor which shows portions.
Issue is likely using say happy hour tutorial updating price list on order added or something and portion reverts to default as ticket price definitikn/list is default.
