If you enable Live Notifications feature, your member will always get any notifications as long as he still on Youzer Pages
It comes with a cool design and a notification sound effect when a new notification is added.
You can control the interval period for checking for new notifications or even disable that feature from the Youzer Panel > General Settings > Notifications Settings.
Why would I want to change the default notifications interval?
If you are using a shared host or a small hosting plan and you chose a fast interval like 5-15 seconds the POST requests can cause high resource usage. To avoid this, the interval can be modified to lower your server resource usage.
