Samsung Galaxy S9 Plus. When I get Gmail notifications the appear on the top of the screen so I can swipe down and clear them or view them. When I swipe to clear a notification it reappears and makes the notification sound again but then after a couple seconds it clears out. This happens every time I clear any Gmail notification. My girlfriend has the same phone and has not encountered this issue I'm guessing it's a setting that I'm missing. Does anyone have a fix for this problem? I receive over 75 emails each day and this little hiccup is getting really annoying. Thank you for any help.
