For initial product syncing this feature is set to Ignore by default. To enable the function to remove products by unchecking Sell on Webstore you will need to do the following:
- Login to accumula.com and go to Apps>Shopify
- Go to the Advanced tab
- Set Non-current product action to Delete
Products should now remove from Shopify once Sell on Webstore is unchecked and the product card is saved.
NOTE: Products using the "Group By" function will also need to be manually removed in Shopify.
