Ring Floodlight no Barcode

I've looked through all the similar questions, so I have low expectations for any real help here. I need to re set up my Floodlight I bought directly from Ring a couple of years ago. There is no barcode or 5-digit pin on the light. Did anyone find a real way to actually set up the light without a barcode? I have the mac address. Don't tell me to contact customer service as that seems useless. If I have to buy a new camera I will be going with a different brand as this is ridiculous and the help section seems to be useless.
