Pathlight won’t connect to bridge

I recently purchased a 4 pack of Ring pathlights from Amazon. I was able to add the bridge with no issues at all. I was then able to add 3 out of the 4 pathlights with no issues and they are working just fine. The 4th light will not add no matter what I do. I have removed the bridge and re-added it, several times. I have removed the app from my phone, rebooted phone, closed all apps, reinstalled and still nothing. I have tried doing it from an iPad and no luck.Is this light just dead and I need to return it? Any other suggestions?
