Turn off prioritization for all apps
Apple’s iOS 27 instructions put the switch in Settings > Notifications > Prioritize Notifications. Turning it off stops this priority treatment. If you only want one app excluded, change that app’s switch in the same list instead of disabling the feature everywhere.
Use the Settings route when the difference matters. A Lock Screen menu can also offer to turn off all notifications from an app, which is a broader change than removing its priority status.

If the option is missing
Priority Notifications relies on Apple Intelligence. Availability depends on a supported device, language, region and software. Apple’s current guide names Apple Intelligence-enabled iPhone 15 Pro, iPhone 15 Pro Max and iPhone 16 models or later; not every feature is available everywhere.
Do not assume a missing switch means Screen Time is broken. If you simply want one app quiet, its ordinary notification settings are the relevant starting point even without an intelligence feature.

Choose the control that matches the problem
Priority ordering, Summarize Notifications and Scheduled Summary are different choices. The first promotes selected alerts; the second condenses text; the third batches selected deliveries. A scheduled Focus defines a quiet window. Turning off one does not mean you turned off the others.
For no notifications from one app, go to Settings > Notifications, choose the app and turn off Allow Notifications. For work hours only, review the apps and people in your scheduled Focus. Preserve the contacts and alerts you actually need.

Example: a shopping alert above your messages
Suppose a sale notification keeps appearing prominently, but you still want delivery updates from the store. First remove that app from prioritization. Keep its normal notifications enabled and inspect which notification categories the store itself offers. Make one change at a time so you know what caused the result.
Check the next ordinary store notification and a message from a willing contact. Decide whether the issue was ordering or the number of alerts. If the store still interrupts you, address its notification settings rather than repeatedly changing priority ordering.
If alerts still interrupt a Focus
Priority ordering is not the same as permission to interrupt. In the active Focus, inspect allowed or silenced apps and people, repeated calls, and Time Sensitive Notifications. Supported devices can also have Intelligent Breakthrough & Silencing. Test routine alerts and necessary contact separately.
An app remaining openable is another issue again. Warden’s access rules do not switch off Apple’s Priority Notifications or rewrite a Focus. Keep notification tests separate from app-access tests.
