When setting metafields, the app now preserves the original case of the namespace and key from the metafield definition. Previously, keys were always sent to Shopify in lowercase — for example, a metafield defined as custom.Fabric_Type would be set as custom.fabric_type.
Now when setting a metafield, the app will first match the case from the metafield definition, and then fall back to the case from any existing metafield values.
Note that Shopify does not change the case of a metafield key once it has been created. If you have existing metafields that were created with the wrong case, they will need to be exported, deleted, and recreated with the correct case.
