You choose whether edits hold your orders from fulfilment

Global settings has a new Order holds section. By default, Tacey holds an order from fulfilment only while a customer's change still owes you money, so a confirmed address correction with nothing owed ships straight away. If you prefer every order to wait until its edit window closes, turn the switch on. Holds show on the order in Shopify with a note from Tacey, come off by themselves when they are no longer needed, and if you release one yourself in Shopify, Tacey records that you did.
