One of the most common reasons why iPhone notifications are not working is because Do Not Disturb is turned on. Do Not Disturb is a feature that silences all calls, texts, and other alerts on your iPhone. To turn off Do Not Disturb, open the Settings app on your iPhone and tap Do Not Disturb
Go to iPhone setting-> Notifications, scroll to find MoeGo app, make sure you turned on "Allow notifications".
If you make any changes, make sure to restart your iPhone.
