Whenever I have Facebook Messenger open, I continue to get notifications for chats that I am presently viewing. That is, I will be reading a chat, and as a new message comes in, I get a peek notification for it even though the chat is already open. Is this normal behavior, or is there some way to fix this without having to hack something out on Tasker?
I don't use chat heads, and the only settings I have on for notifications are Notification Previews and Light (LED).
On Android 7.1.1, though I had this problem on 6 on my previous phone as well.
