How to be invisible on whatsapp? It’s related to a specific user and a specific group.

I don’t want to block that user and don’t want to quite that group.

Whenever that user send me a content (text, image or video) or whenever anyone share a content in a group; I want to see all contents but I do not want them (a specific user and members of group) to know that the contents have been delivered to me and I have seen the contents.

Also, if I am online, I do not want them (a specific user and a specific group members) to know that I am online.

Please let me know.

What settings are required for both?

Regards

There are apps that get around the limitations you mentioned, and they're able to retrieve the messages without you opening WhatsApp.

There are many similar apps on the play store, one of them is called private read for WhatsApp it displays the messages and media in it's own app without you having to open WhatsApp, this way you can view the content without the other person knowing. I've never tried the app, and so I cannot vouch for it's accuracy.

As for hiding the fact that you are online while using Whatsapp, you should first disable your last seen from WhatsApp settings, and then, every time you want to open WhatsApp, you should put your phone into airplane mode. That way no-one will be able to see that you're online. (The messages will be sent after you exit WhatsApp, and go out of airplane mode)
