I'm assuming that Facebook is a "web application". Please let me know if I am in the wrong forum. I already tried asking this in the Facebook community without a response.
When I open the app and tap "People" on the bottom, it says I have one new notification. How do I check it? Tapping on either icon doesn't do anything.
I'm using Messenger 218.104.22.168.120 on Android Oreo 8.1.
