Google assistant only recognises HA devices when I speak

I got a Nabu Casa cloud account and enabled the cloud Google Assistant integration. I can now control all the HA devices with my voice but my wife, who is a member of the same Google Home, cannot.

When I click on SYNC ENTITIES TO GOOGLE the HA devices show up in my Home app on my phone but not on my wife’s phone despite her being in the same Home.

How do I fix this?

Have you tried syncing on her phone? No idea if that makes a difference or not as I have not used Google home for over a year now.

Not sure what you mean. When I did SYNC ENTITIES TO GOOGLE I didn’t specify a phone.and voice activation worked for me before I did it. My Nabu Casa account uses the same gmail address as my phone account, so I assume that is how it made the connection.
