I migrated my Nest doorbell from the Nest app to Google Home app recently. Familiar face detection which was working perfectly until then has completely failed after that, there has been only 2 detection in last 1 week and that too inconsistent. It detects the person but no face detection, although the library is same, familar face detection is on, zones are selected, notification is on, nothing has changed, lighting is same, before the help desk says to check the same old things. It's the app issue. It should have worked as before, but something with the alogrithm has completely screwed my doorbell. The experience is so bad, I am regretting this migration as I use to keep an eye when my kids are home from school, now I don't get any notifications.

No help, but exact same issue here. Migrated from Nest to home and now facial recognition doesn't work at all. Tried deleting face library and cycling settings to no avail. This migration experience sucks.

Also upvoting this as I'm experiencing the same issue since migrating to the Google home app. The doorbell camera will correctly notify when a person is detected, but very rarely identifies the face, even when looking directly at the camera and pressing the doorbell.

Yeah same issue here only 2 people recognised since switching a few weeks ago worked perfect on the nest app

Same here after migrating from the Nest app to Google Home app, familiar face detection performance is very poor. Tried everything possible but as stated from Google help but problem persisted.

Ya I am in the same boat. Only had 3 face detections since migrating, door gets used multiple times a day and never detects a familiar face. Doesn't seem like there is any solution for this issue yet.

Update
Following my last post, after 5 years of use, I've had to replace my Nest Doorbell as it was intermittently losing power. I've purchased the latest Nest Doorbell (wired, 3rd gen) and kept the same database of familiar faces. Identification of familiar and unfamiliar faces has started working fine.

Interestingly they want us to get the new hardware then

Thought I'd add my 2 cents - same experience as others here - total failure of the facial recognition after migration. I have a 1st generation wired Nest Doorbell. I also have a Nest Cam (battery) in my garage and it has no trouble identifying faces with the same face library.
