Adjust notification settings

My mobile and desktop apps are out of sync with notification frequency and I get duplicate pings. Adjust the notification settings so desktop notifies only for Important mail, mobile notifies for All mail, and both devices respect Do Not Disturb between 22:00 and 07:00 local time. Apply these settings to my primary account and confirm when a test message triggers the expected devices.

Before I change notification rules, make the impact clear for my team. Summarize how many messages per day would trigger desktop Important alerts versus mobile All alerts, list three senders that would cause cross-device duplication, and recommend a simple rule set that preserves urgent mobile notifications for on-call staff while reducing desktop interruptions for heads of department.

I altered notification settings to reduce daytime interruptions, and overnight the on-call engineer missed a server-down alert because their mobile notifications were set to quiet. I don’t know which device or setting suppressed that alert. I’m afraid SLAs will be breached again. What’s the most likely misconfiguration, and what immediate settings restore guaranteed mobile critical alerts for on-call while keeping noncritical traffic quiet?

I repeatedly tweak notification settings for myself and my team to chase the right balance of focus versus responsiveness, and every tweak creates confusion about who will see critical alerts. Where am I losing credibility and causing missed responses, and what single notification governance rule will stop the constant fiddling and make alert behavior predictable for everyone?
