When an item’s duration is “30 days” it cannot change to OOS neither on HGR nor your eBay store. If you ever want to change it through HGR, you will get an error message directly from eBay. In order to prevent this, we recommend you to enable the “Out of stock action” that increases the item’s price when being OOS on supplier. You will find this setting under Settings>Account.
