If I’m not at home and someone sends me an important message on WhatsApp / SMS/text message, there is an issue: if I open the message, I will not see it as unread at home.
The solution is simple: copy & paste the message to a notes app, and, also, always reply to the message with a question, asking for a reply.
Thus, when you get the second message, you will have an unread message at home.
