@InsightSupportTo ensure you don't hear notifications from other apps during your session, please turn DnD Mode on.
iOS: You will need to turn on DnD Mode through your iOS device settings (Remember to disable this setting once your session is complete).
When DnD is on, you will see a half moon icon in the iPhone status bar. There are two ways to turn DnD on / off through your iOS settings.
1. Launch iOS Settings > Do Not Disturb > Turn on Do Not Disturb or set a schedule.
2. Open Control Center, then tap the half moon icon.
Android: This can be done within the app's settings: Profile > Settings > Timer Settings > DnD Mode.
This setting will mute system sounds during the session and will return to a normal state after the session is complete.
