When I unblock someone on WhatsApp, can they see it - briefly?
When you unblock someone on WhatsApp, they cannot see that they have been unblocked. The action of unblocking is not visible to the other user.
When I unblock someone on WhatsApp, can they see it - in detail?
When you unblock someone on WhatsApp, the person you have unblocked does not receive a notification or any indication that they have been unblocked. The action is entirely invisible to them. This means that even if you decide to re-establish contact by sending a message after unblocking, the other person will not be alerted to your previous blocking action unless they were aware of it through other means.
WhatsApp prioritizes user privacy and ensures that such activities are kept discreet. Unblocking someone simply removes the block, allowing future communication to flow as if the block had never existed. However, any messages sent during the time the person was blocked will not be delivered retroactively; they will remain undelivered.
In summary, unblocking someone on WhatsApp is a silent process that does not inform the other party of your action. This design helps maintain a smooth and private user experience on the platform.
