Help Samsung Galaxy S7 with Android 7 Nougat: Apps does not notify or are very late


Hi all,

after my S7 has been upgraded to Android 7 Nougat, some of my more crucial apps such as gmail, Google Keep, and my calendar, does not gives reminders and notifications.

At first, I thought it might be the "new" feature Doze, even though it has been around size Android 6 Marshmallow. However, after disable the Battery optimisation for those apps, they still either does not notify or comes hours after a reminder has been set (it sometimes seems like it only kicks in and start syncing after I activate the phone)

It has already costed me some missed meetings and appointments.

Can anyone shed some light about what's going on with this update and how do I bring back the "sync" and "notifications"?
