Ignore this question. You guys already thought of this and have a solution in the settings section of your plugin. 😀
We updated the plugin, tested a transaction but additional fields were not shown. The site needs to get a dispatch date from the customer, so we need to return a date back to the orders section. Currently when we add an extra field in getting a user to input a date, this isnt returned when using paypal express.
The only fields that are accepted are default fields + the user_comment (note)
Kind regards
