Full Screen Blocks Notifications

I use pomodoro timer apps primarily to help me work during the day while using Scrivener. It seems as though full screen composing mode in Scrivener seems to block notifications from other apps that I have. And while the notification should override the full screen setting, the timers don’t seem to work (chime when they are supposed to chime telling me that the timer is up) when I’m using Scrivener. I originally thought it was the timer app that was the issue. But I’m beginning to wonder if Scrivener is the issue. Hope to hear from someone soon.
