I’ve recently upgraded to Magento 22.214.171.124. I have a simple custom module for keeping track of salesreps on customers and orders. Until the upgrade, it worked great, but magento 126.96.36.199 changed the way customer attributes are handled in the admin, The attribute needs to be in the customer_form_attribute table. I’ve run the code from this post to add the attribute to adminhtml_customer which restored the field on the customer account page, but when I added it to adminhtml_checkout it did not show up on the backend order creation page.
I can confirm the attribute IS being loaded into the $data array, and when creating an order for a customer with a salerep already assigned the salerep is copied to the quote, order, etc. but the dropdown just isn’t showing up on the order creation page. And of course I checked that the fields are indeed in customer_form_attribute.
Do I need to add this to the customer forms in customer_form_attribute (customer_account_create, customer_account_edit, etc?), or should this be working as is?
