Not receiving notification in mobile data

[FM999]

Suddenly after latest update, Im not

reciving notifications when on mobile data, yet

when I connect on WiFi, all of my notifications

then pop up at once? Gmail, WhatsApp, news

etc. I'm not getting notifications when l'm on

cellular data but when I connect WiFi all

notifications popped up.

Just to check if it is operator issue, I have tried the sim in another phone, it was working fine.

My data saver and power saving mode is off, still I can't receive notifications

Go to Connections, Data usage, Allowed networks for apps. Check if Mobile or Wifi option is selected for each app.
