If you use the Nova Launcher as an alternative to a pre-installed launcher, such as TouchWiz, Samsung Experience, Emui, etc., then it is possible that it does not display any App Badges or App Symbol indicators.
If this is also the case with you, then this is due to the Nova Launcher. Fortunately, this can be solved very nicely by proceeding as follows:
However, you may have to spend less money for this:
1. You need the Nova Launcher in the Prime Edition. If you haven't already done so, it's best to purchase it from the Google Play Store.
2. Next you need the app "Tesla Unread"
This app is free again and offers you the option to display badges in the Nova Launcher App.
Now install this app and configure it if necessary.
After that the Nova Launcher will finally show you the app's symbol indicators with numbers again.
