Extension only turned on one device

I recently was trying out the 1Password Safari browser extension on my Mac. I noticed it alerted me on my iOS. And seemingly auto-turned it on. I dismissed the notification as I did not want the extension on my iOS device. So I had to go back and turn it off on my iOS device.
I came back to my Mac and discovered the extension turned off.

Is this expected behavior? Can you not have the extension turned on a single device? Further can you turn off this feature that it auto turns it on and off on other devices?

1Password Version: 8
