Android and iOS Buy SDK accessing metafields

Hi, I have an issue regarding accessing metafields both query and mutation for Android and iOS Buy SDK.

Specifically, I want to add extra fields for customers and orders, where the app can actually mutate the metafields. For example, the customer can add a specific setting to their user setting and add a delivery time to their order.

If anyone can provide any pointers on what I should do would be much appreciated. If you need any more information please let me know.

I’m not too sure about adding customer settings or options (though there might be a way). But adding them to the order could be done through cart/checkout attributes. You could add the attribute of requested delivery date to the order/checkout object and then it would be handled on the fulfillment side of things. Hope this helps.
