With the latest update, notifications are not showing UNTIL I open the app. I have four Gmail addresses on this phone. When I open my most used, all other accounts "light up" if emails are waiting. This is inexcusable! I have a Samsung Galaxy E20 5G. There is a bug that fights with the latest OS update. Fix it! There are others with the same issue. Don't bother using your standard "see this article" response with me. The problem does not lie with my settings but with your buggy app!
