Metafields in Shopify enable you to customize the functionality and appearance of your Shopify store. You can use Metafields to add specialized information to parts of your online store.
Currently, Polar does not allow for users to filter by Metafields within the app due to volume. However, most Metafields can be found in tags, which Polar does enable you to filter by in Custom Reports.
If you have any questions about your tags and using them to filter your data, please don't hesitate to reach out to our Support Team via the in-app live chat and we'll be happy to assist.
