Where can I see delivery instructions from a Shopify Local Delivery Order?
Based on what's available from Shopify's APIs at the moment, delivery instructions text entered into a local delivery order isn't accessible. Third-party apps (including ours) can't access this text directly. For more, here's a thread - this has been missing functionality from Shopify since June 2020.
We have been in touch with Shopify regarding when they would make that accessible and also we have let them know that this generally isn't a great experience for all merchants. As soon as they have it available, we'll be showing this data on EasyRoutes.
For now, if you put that information into an Order's notes section, we show that in the route and for the driver (more on Driver Notes here). It's also possible to collect instructions via order notes this way in most themes. (e.g. see "Enable cart notes" on Shopify Help Centre).
You can also persist information for a customer using the Customer note feature on Shopify -- you can enable your orders or routes to show this data in your Settings.
