First, please make sure you have enabled push notifications in your phone. Here's how:
1. If you are using an Android phone, go to your phone's "Settings" -> select "App" -> find the "Whova" app in the list and click it -> check the "Show notifications" box to enable it.
2. If you are using an iOS device, go to your phone's "Settings" -> select "Notifications" -> find the "Whova" app in the list and click it -> enable "Allow Notifications".
After enabling push notifications in the phone, you should also make sure push notifications are enabled in the Whova app.
To check it, simply open the Whova app and click the "Menu" button at the top left of the screen -> click into "Settings" -> enable notifications for "Event Updates" and "Event Activities" depending on your needs.
