I'm using it but the fact the the assitant can only respond for the active google account is driving me nuts.

The Google Calendar app from my Google Pixel merges all my accounts but yet, the assistant is linked to my Google Account instead of my device.

It's useless because I'm using multiple calandars on multiple accounts.

Same issue here. They have features like "okay google dial into my next meeting," however it doesn't work since my phone's primary account is my personal account. Assistant doesn't work with my secondary work account.
