You all know about whatsapp delete message
if you don't know after sending a message to someone in whatsapp you can delete the message both for your phone and the person you sent it to But do you know that
WhatsApp’s ‘Delete for Everyone’ feature won’t work if someone quotes your message before you delete it.
If someone has quoted your message on WhatsApp before you delete it, you will still be able to see that message -- rendering the ‘Delete for Everyone’ feature ineffective, The Next Web reported.
The report further stated that this isn’t a bug but instead is a part of WhatsApp’s feature. Also, there is no mention of how the feature works in cases of quotes in the WhatsApp’s FAQ.
How it works
WhatsApp allows users to delete messages sent by mistake within seven minutes of sending it. You can do so by tapping on the drop down icon of the message and choosing “Delete for everyone”.
However, if within these seven minutes, that message is quoted then the original message will successfully disappear but the deleted text continues to show in the recipient’s quote. Here, quote means replying to a particular message.
For example if you reply to a particular message before the person deletes it, the quoted message will still appear on the chat. While you can still delete the original message, the quoted message prevails. A screenshot is attached below to make things clearer.
