Here you go guys. Thank me later
So if you’re using an S8 and you don’t want to miss important messages from your favorite apps, here are the steps to fix the problem:
1: go into settings, search for “apps” (wait a few seconds for the setting page to load because Samsung’s software is laggy) and click into it.
2: once inside “apps,” hit the three dots on the upper right corner, go into “special access.”
3: once inside special access, go to “optimize battery usage.”
4: from here, tap on the dropdown menu saying that says “apps not optimized” and switch to “all apps.”
5: once all your phone’s apps are shown, find the apps you want to receive notifications as they come through, and tap on the switch to turn it off.
(This is weird, right? You have to turn off the switch to ensure the phone doesn’t automatically kill your app, so you can get notifications on time)
