Shopify Exchanges Update

Has anyone noticed that Shopify appear to have updated their exchange process. This now all seems to be done inside the original order, as opposed to generating a new order (for the new items) and using Exchange/Credit as payment method against them.

This is great for Shopify, but it means exchanges are no longer syncing correctly to Dear. Additional Payments/Credits are coming through as well as the restock. But any new items added are not syncing through to Dear.

Has anyone else discovered this. Sorry if it's already been posted, but I couldn't find any mention of it elsewhere.
