[Galaxy S II Android Development] laptopu:
I'm having problems with notifications. I don't receive any app notification when the screen is off not charging. That mainly means emails for me which is really annoying.

I have greenify and tried whitelisting gmail app, nothing. I have set battery optimisation off. It's the same with stock email app.

I have noticed the first time I go to settings-notifications then try going into each option I occasionally get a crash message as follows:

java.lang.ClassCastException: java.lang.Boolean cannot be cast to com.android.settings.notification.NotificationBackend$AppRow
