Why aren't notification numbers showing on apps anymore

[Android Central Question]

so after the most recent update most of my apps no longer show the number next to the top left corner. like messages app and say 15 unread messages, it'd show a 15 next to the top but for most apps its gone. the app icon badge setting thing is on as well. is it because the notifications are blocked because some are blocked

What phone? What update?

I am seeing the same thing on the stock samsung email app. (Note8). After I installed Oreo, there was an update to the mail app. Since then, no more notification badges on the mail app icon even though I have that feature activated in the app settings.
