We would need to know what you mean by "live history option". Is this in the Google Nest app or the Google Home app? Do you mean the "History" option or the "Live" option at the bottom of the camera screen in the Google Home app? Or do you mean the "Full history" option that displays after you select "History"? Is your camera or doorbell wired or battery powered? Or do you mean the timeline/sightline in the Google Nest app? Do you have a Nest Aware or Nest Aware Plus subscription?
If you can still see the equivalent forward and backward fast forward symbols for the same camera(s) on the home.nest.com website, then maybe you could try deleting and reinstalling your Google Nest app. On my iPhone right now, the forward and backward fast forward controls are still present in the Google Nest app.
