Why do I keep getting alert notifications but I don’t see them when I open the app?

I see the notification for an alert on the lock screen but when I open the app there are no alerts listed.

Try, Updating your app

1. Check that you have the latest version of the app
   a. Go to the app store and check if there is a version update, if there is, it is recommended to update
2. Try reinstalling the Alertable app
