Google Confirms Nest Hub Bug That Misreads PM Alarms as AM

The glitch weakens trust in voice readbacks on the smart display and pushes users to check the screen after setting afternoon alarms.

Overview

Owners of the second-generation Nest Hub report the device says a PM alarm is set for AM even when the request is made in the afternoon.
Tests show the display lists the correct time and the alarm rings as planned, which points to a speech-only confirmation glitch.
Google, in a Nest Community note reported Friday, said it has identified a fix and will announce when the update rolls out.
Early checks did not reproduce the problem on a Nest Mini v2, suggesting the issue is limited to the second-generation Nest Hub.
Until the patch arrives, users who set afternoon alarms should glance at the screen to confirm the time to avoid doubt about important reminders.
