The primary reason users notice this tag involves iOS Focus Mode. Whether you run a customized Work setup, Sleep profile, or standard Do Not Disturb bypass, Apple applies strict filtration to incoming pings. Regular app pings are silenced instantly, routed away to your notification center without waking the display or triggering haptics.
To prevent users from missing genuine real-time interactions, Apple gives third-party developers access to bypass rules for high-value alerts. When you enable a Focus profile, iOS scans incoming communication metadata. If Snapchat flags an event as immediate, the system displays the banner alongside an explicit tag reminding you why it broke through your active filter.
The notification badge serves as an explanatory label: iOS is telling you that this item skipped your silence rules because the developer categorized it as urgent. Once Focus Mode turns off, the explicit "Time Sensitive" tag frequently disappears, reverting to a standard lock screen alert.
