The notification settings allow you to control how many notifications you get. This video shows how you can set your notification settings.
Make sure your notification settings are correct
Remember you will not be notified about notes/tasks you create yourself. This is by design.
Notifications are also controlled at your device level. Make sure you have notification turned on for HelloShift. If you are not sure, re-install the app and accept the prompt during installation for receiving notification.
If none of this works, contact us and provide the note or task you did not receive notification for.
