I don't receive any notifications from the Google app anymore after the oreo update on s8

[Android Central Question]

Hi, I am using an unlocked Samsung s8.
I used to get some informative notifications from the Google app before the update. Like weather changes. Travel notifications. Traffic notifications. And many more.

After the oreo update, I don't get any of them.

Can anybody please help?

I also want to add that many times I get a notification. I see it in the always on display. Then suddenly it vanishes. I've seen them vanish while seeing the icon too.
