The most likely cause of an item not showing up in inventory on one of your devices is a connectivity issue. The device causing issue may not currently be connected to the internet, or it has lost its connection to our servers. To fix this, restart your Clover device. Once your device is restarted, close and re-open the Items with Variants application on your Clover device. Your items should then sync to the device.
If the above steps do not resolve your issue, please contact us at firstname.lastname@example.org so that we can further assist!
