I have been facing a issue with notification for few of the apps like whatsapp family. Etc 

I have checked all the Notifications settings and still I ended up not getting notification of whatsapp

Check if you add WhatsApp inside sleeping or deep sleeping apps...if added, then remove it
Also not forgot to check and toggle on..."Allow background data usage" and "Allow Background activity/battery usage" inside app info of WhatsApp
