WhatsApp messages are not appearing in chronological order When in a group chat, if many messages are exchanged between other people in the group, when I check my Whatsapp, the messages are grouped according to sender and not chronologically. I know that my phone isn't the problem as I have recently changed my phone, however, I'm still experiencing the same problem.

I have tried uninstalling and re-installing WhatsApp on my phone, and the same problem still occurs.
Recently, I have seen many asking the same question in different places but I couldn't find a solution anywhere. So I decided to contact the WhatsApp team directly addressing the issue few days back. This is the response I received:

WhatsApp Support
