After Android 9 update I am not able to keep some apps active in background when you turn off the screen (phone in stand-by) stopping to receive notifications in apps like Whatsapp for Business, Outlook with an Exchange account.
I have already tried to turn off "Battery management" and to set for these apps "dont optimize the Battery" but all these settings not work.
With Android 8 it was present in settings "Power safe manager" in order to have these apps active in standby mode but this menu item is not present anymore in Android 9 settings.
Please help to find a solution, for sure it affects all users.
You need to do 2 things:
- Go to Android settings > Smart Assistant > Appblocker. There you can choose: 1) switch off the Appblocker, or 2) Give exceptions to particular apps.
- Go to Android settings > Duraspeed and again to options: 1) switch off Duraspeed or 2) Give exceptions to particular apps.
Hope this helps.
