Whatsapp chats disappearing randomly In WhatsApp, random messages are disappearing from chats chronologically. Messages from earlier dates are missing. Not all of them disappeared. It's happening randomly. Like if i asked somthing on WhatsApp, the reply of other person is missing. Also, its happening with messages from both me and the other person. I tried reinstalling whatsapp with and without backup..but it didn't help. I have been facing this issue for last month when I port my number from IDEA to JIO. M losing important stuff due to this issue. Please help.
Do you see anything like "this message was deleted"?

If yes, it means that the person posting the message has deleted it for all users.

Otherwise, whatsapp doesn't delete messages unless your phone is accessed by someone who intentionally or unintentionally deleted the messages.
