Connecting Eufy Video Doorbell with Google Nest Hub Max

I just got my Eufy 2K wired Video Doorbell. It works good at least as good as the one before it (would not work with Google Home). When I try to connect it with my Google Home app:

I select New Device > Works with Google > Find the Eufy Security app in the list > and it comes to the login screen. It will not log in. Gives me a Login Error Code: 18201.

I thought I had maybe got the P/W wrong, so I go back to the Eufy Security App, select my region (again) type in my email and P/W and get a “robot challenge” and it logs me in, so the P/W was correct.

Anyone else have this issue and overcome it?
