To my knowledge, on a preexisting Shopify B2B order, it is currently impossible to add a PO number or edit an existing PO number. Am I missing something?
@scottstilson you can use custom metafields to save more information to an order.
Let me emphasize, since I mentioned it only in the title, that this question has to do with adding or editing PO numbers on the mobile app.
B2B orders have a PO field under order number field on details page, which is also available in the mobile at the exact same location. You may need to scroll to the bottom to see it when you are on the order details page. If you need store additional information, you can create metafields and still edit them using the mobile app at the very bottom of the page. Hope this helps!
Are you able to provide a screenshot from a mobile device showing the PO field? I do not see it.
It’s not on the mobile app yet, just have to ask Shopify support and eventually the mobile app team will add it. We suggested it to them a couple months ago
