Cart properties accessed within a Shopify POS UI Extension appear to be out of sync and consistently lag by one update.
When a cart property is added or updated, the extension does not immediately receive the latest value. Instead, it reflects the previous cart state. This was reproduced by:
-
Adding/updating a cart property
-
Displaying the same cart property via a separate POS UI extension
In all cases, the displayed value was one state behind the most recent update.
