Default destinations
There's no separate "default" field - it's just the link's destination URL.
GoloLink doesn't have a distinct "default destination" setting. A link's regular Destination URL is what every visitor gets unless a geo or device rule specifically overrides it for their country or device.
So to change the fallback, edit the link's destination itself - your geo/device rules don't need to be touched.
