Another issue I have with the chats is that there appears to be two ways to read and talk in a chat room, and only one of those two ways clears the blue bubble notifications.
Consider:
These two pages give access to the same chatroom. If someone talks in the chatroom, it increases the number in the blue bubble:
If I read their message through the page Chat room, then it decreases the number in the blue bubble accordingly; but if I read their message through the page Tournament page, then it doesn’t decrease the number in the blue bubble.
So, the number in the blue bubble is absurdly high for me, because it never gets cleared, even when I read the messages.
(The links above are for the chatroom of a tournament, but same goes for the chatroom of a group: then the chatroom can be accessed either through chatroom page or group page )
