I receive a notification and open it. The notification remains in the status bar until I go and open it again to finally remove the notification from the upper left corner. It happens with various apps on my Galaxy S9+. I receive a GroupMe chat and open it to respond. I close the response and the GroupMe notification remains on the status bar. I swipe down to see my notifications because I think that someone responded again to my chat and the notification finally disappears from the first response. Very annoying because in chats where there are a lot of back and forth discussions I am constantly having to open my notifications bar to see if someone has responded or if it was just the original notification that hadn't cleared yet... Please help. Thank you!
