Hi, I have the flits app installed which customers can update their Birthday (see attached screenshot) I plan to collect this information to provide Birthday discounts. However, customers have to input their birthday through the account. I would like them to do this upon signing up to the site through the sign up form. What would be the best way to automate this and store the data on their account. Would I be better installing another app, or adding fields to the sign up form then using code to store the data they input onto their account?
