Here's how to enable the notifications from Atlas when you have a Samsung device.
The path shown below should be the same in all Samsung devices. If you don't find the same steps, you can always refer to this website, which will explain the path according to your operating system version.
1. Open your settings
To do so, either swipe down on your screen in order to display a gear at the top-right of the screen or look for the gear icon in your applications menu.
2. Apps
Once inside the Settings menu, you can click on Apps, then scroll through your list of installed apps to locate Atlas Scheduling.
3. Notifications and battery
Scroll through the options and select Notifications, and ensure that Allow notifications is toggled on. You can also set your preferences on how these notifications are displayed.
Once this is done, go back to the previous menu and scroll through and select Battery, ensuring that this is set to Optimized. You can also select Unrestricted, but this will reduce your device's battery life.
