S Planner doesn't show birthday notifications

[AC Question]

Hi everyone,

I'm using S7 edge.
In contacts, I saved all date of birth of my friends.
The point is S planner synced it but S planner doesn't show any notification on notification bar. If I wanna see it, I have to access the app or using widget, but what I is ring an alarm or at least show a notification.
Please tell me how can I get rid of it?

Are you using an app killer/ battery saver app? If so, add S planner to whitelist

Probably Doze so the OP needs to remove SPlanner from App optimization
