I agree with this but I add to select all apps option

Maybe you have to set Security - Data - App Network Management - Background - Allow background data connection for these apps. Try it and post your feedback, it's somehow important to know if these settings are worth it.

After some R & D. I set storage option in app permissions to "Allow" and it worked for me but for some apps you have to choose "always running in background" option. That worked for Microsoft apps.

I am also facing same problem. No notifications from gmail, outlook, zoho mail, sometimes whatsapp too. Please help. Bugs are annoying me, how can I recommend someone meizu if basic issues are not resolved. There is some single thing needs to be fixed here which is blocking notifications. I tried old solutions on flyme 6 but options are changed now & not working.
