iPhone 7 is not showing notifications for a incoming messages in Messages application I have iPhone 7 running iOS 11.2.5

iMessages (Messages) application is not displaying any notifications for the messages that is coming from bank.

I checked all the settings for notifications and messages app. All of them are enabled.

Some threads on Apple Community forums says that you need to disable bluetooth. 

I don't know. Anyone is facing the same issue?
If your iPhone’s date or time is incorrect, that could be the reason why you aren’t getting notifications or alerts promptly.
