It’s seems I’m receiving notification from some apps.
Only when I open those app or it runs in background,
I receive notifications of that particular app
(It seems like , I just connected my device to internet and notification starts to pop in of that particular app ).
I’m attaching two screenshot.
When battery optimization is set to INTELIGENT CONTROL , I receive no notification of that app untill I open that particular app or make it run in background.
Only if I set each app’s battery optimization to DON’T OPTIMIZE, then I receive notifications like before.
But it can drain my battery much faster.
So that I can receive notifications normally and keep my battery optimizied.
