Was this the first time an early warning system actually sent a warning before the quake? Heard from friend that warnings went out.

If you define early as being before the earthquake struck then yes it did in fact warn me before it struck. However, I would not consider 1 second before the earthquake striking early but hey it at least warned me.

My experience as well - I wasn't sure if the vibration was my phone or the quake

Before the earthquake struck your location. The alert was triggered by an earthquake already occurring somewhere else, it wasn’t predicted.

I received a notification from the MyShake app during the earthquake. I was also in a Zoom meeting at the time, when another participant said, "Woah" while looking about the room before the seismic vibes hit me.

Zoom a better early warning system?

I got the alert on my pixel about 5 seconds before I felt it in Oakland. Wasn't a big jolt. More of a gentle swaying for almost 30 seconds.

Maybe in the US.

The systems have been in place in Japan for a while longer.

There was a 4.1 a month ago in the north bay that also had warnings go out to 4 (iirc) counties. It beat the shockwave in most locations.
