The thesis
Most WhatsApp tools are a shared inbox with a campaign sender bolted on, and a contact list that matches neither.
So the same customer exists three times over, and the person actually replying has the least useful copy.
Conecxt was built the other way round: one customer record, and every part of the product reads and writes that same one.
It sounds like a small thing until the day you need to know what a customer was told last week.
