Limitation:
Due to WhatsApp limitations, some existing conversations may not sync correctly during a rescan or resync with ChatDaddy. As a result, these chats may be recognized as new, causing the system to classify them as new clients—even if no messages have been sent or received. This can trigger a “new chat” event.
