Adjust the notification settings of a single or group chat in the iOS app as follows:
Open the desired chat, and tap the title bar. Then, tap the bell symbol in the detail view of the contact or group to open the notification settings.
Activate “Do Not Disturb” to disable notifications (for a certain duration). In group chats, the option “Notify When Mentioned” is available. If activated, you will only receive notifications for messages in which you are mentioned.
To mute notifications, deactivate “Play Notification Sound” in the detail view under “Notifications.” You will still receive notifications, but no notification sound is played.
