There’s a notification centre in the app. You will discover it through the Bell icon in the top right corner next to your profile icon on the home screen.
It helps keep track of all your messages and not to miss any news. You will never miss info about a ganapuja for example, because you will always have it in your notification centre.
There you will find all kinds of notifications: e.g. when the event you plan to go to is coming soon or it was changed or canceled, when someone messaged you, when someone reacted to your post, when there is a new post in the section you follow, etc.
You will see there is a new notification when there is a red point on the bell icon. You just click it to open and read the new notification. (If the red point does not disappear afterwards, then you can refresh the app by swiping down the length of the home screen.)
