‘Do Not Disturb’ feature on Android OS is used at night to block notifications, SMS messages and calls (except for numbers marked as favorites). This feature also blocks any Blink motion alerts.
It is possible to use ‘Select Priorities’ to allow specific Apps (“App notifications”) to override the Android ‘Do Not Disturb’ function, but Blink does not appear in this list.
Other add-on Apps I use appear in the “App notifications”, for example ‘Beoplay’. This seems to be a lack of a bell (or whistle) between Blink and Android. My device is currently running Android 8.1.0.
The only solution to receiving Blink notifications is for ‘Do Not Disturb’ being disabled permanently.
