Under Settings | Events | Seen events for your doorbell in the Google Home app, if you select an activity zone, do you have People or Animals or Vehicles or Motion turned on? If you do, your doorbell should be flagging those as events in your history. And if you have "Your notifications" turned on, you should also receive notifications. (In the example below, we are NOT receiving notifications because they are turned off.)
Do you have a Nest Aware or Nest Aware Plus subscription? If you do NOT, then you will only see events that occurred in the most recent 3 hours.
Are "Push notifications" turned on under "Notifications"? You could try deleting and reinstalling the Google Home app. I had to do that earlier this year when I quit getting notifications. Are there detectable events that are occurring? That is, if you walk in front of your doorbell or ring the doorbell, is an event recorded?
I'm almost out of ideas. Is your doorbell in the same Google Nest "home/structure" that your phones and iPad are connecting to? If you view the doorbell in the Google Home app, is it always "Live"? Can you bring up the camera and turn on the microphone and talk with someone at the doorbell? If you bring up the doorbell and select Settings | Video, what does it say under "Video History"? If you select "Video History", which option is checked?
