YouTube Version 6.5.2 Sign In Problem

I have just configured a new Android box (EZ Media) with Kodi 18.5 and added the YouTube addon ver. 6.5.2. When I attempt to sign into my account, I get the normal "you must enable two apps" message. As I have always done before, I then go to the Google device login site using a laptop and enter the code on my Android box display. It works fine and brings up a second login code. When I enter the second login code via my laptop and confirm my YouTube account, I get the message:

"Sign in with Google temporarily disabled for this app. This app has not been verified yet by Google in order to use Google Sign In."

The addon works normally for searches, popular right now, and live events. But, I am unable to see my subscriptions and their associated new videos.

I have an older AVOV box running the same YouTube ver. 6.5.2 and Kodi 17.6 which works perfectly.

Does anyone know if there is a conflict with this addon and Kodi 18.5?
