When I look at my 'activity' page it may show more than one reactions & replies to a single conversation.
When I click on one of them, it takes me to that conversation; I am not sure how other people do things, but when I'm in that conversation I read all replies. I don't read that one specific reply and then go back to the activity page to click on one of the other activity notifications that takes me back to the same conversation.
So as a result I think it makes more sense to me if ALL the activity notifications for that one thread go to a 'read' state after clicking on one of them, instead of staying 'unread'.
Does this make sense? Anyone else have thoughts on this?
