When suppliers don't have allergens up to date users can set ingredient allergen values manually. But when suppliers start sending allergen information I would like to know that so I can make the choice to accept it or keep using the manual data. Same can happen when suppliers update this information, I would like to know that.
This can be applied to all data used on ingredients coming from a 3rd party.
What do we do when a message is displayed? Does the user have to accept before we close the message? Do we only display the message once? Can be a lot of messages for a user.
