Echo show 10 appears in Ring app but not my show 8

I linked the Ring and Alexa accounts and apps successfully and enabled Ring as a skill in my Alexa app. In the Ring app my Show 10 appears. Both my Show 8 & 10 are enabled in Alexa and the Ring cameras and doorbell pictures appear in both 8 & 10. Under find Alexa enabled devices and after invoking a search for enabled Alexa devices the Show 10 pops up but all I see is the message "cannot find alexa enabled devices" rather than the Show 8! Strange! Called Amazon and they confirmed the Alexa side shows both Show 8 and 10 enabled. Is there a glitch with the Ring app. I an located in Southern California Any advice?
