Notification Not Working – Countdown+ Calendar (Lite) Review

I'm not giving a bad review because I know it's not whoever runs this app's fault that the countdown notification on the app can't be a thing. But I'm here to let whoever runs this that the new feature of getting a physical notification for the countdown doesn't work. I waited all day and didn't get anything for the 2 concerts I have counting down.
