User A: Creates a topic
User B: Posts a reply to the topic
User C: Immediately after user B’s response, sends a reply to user B.
At this moment, a notification is sent to user A and user B, informing them that they have a new answer in the topic. User B realizes that the answer belongs to him, but user A, because there is no sign of replay, does not know whether user C’s answer was for him or for user B!
This problem is exacerbated in large threads and confuses the creator of the topic.
I think it would have been better if the replay sign had not been hidden during successive replies, and it would still have been clear to whom the reply was sent.
