Notifications getting delayed

[the_good_doctor]

I am using a galaxy m51. When the screen is in sleep mode, the notifications(whatsapp/mail) are delayed by 10-20 mins. This is not due to network issue, as i am using a pretty good one. How to fix this issue? TIA

Make your device power off and on and check.

This issue is recurring for a few months. So there has been a lot of restarts and the problem isnt solved, certainly.

Then try to check notifications option on settings
