Google assistant

I'm hoping by the morning. Also hoping that sideloading an update to Google play services didn't screw with anything.
Nothing updated before it hit. I just long pressed the circle button and this popped up. It's definitely a server side switch.
 
When I switched to another Google account, the Assistant wasn't there, not even in the settings. When I switched to my main account, there it was.
Holly crap you're right! 2 out of the 3 accounts I have set up on my device have it available to use. Just not my main account. That parts Hella annoying..
