Why the export changed
WhatsApp messaging by username has started to reach some customers, so a few may message you without sharing their phone number. Mersal recognises them by their WhatsApp ID, so the export now includes that ID and the customer’s username. That way every contact can be identified in the file, with or without a phone number.

About WhatsApp IDs in the file
A note in the file explains that WhatsApp IDs only work for your business. They can’t be used in another tool, and they aren’t phone numbers.
A customer’s WhatsApp ID stays the same if they change their username, and changes if they change their phone number.
