What is "if you block and then unblock someone on whatsapp?

After you block someone on WhatsApp and then unblock them, here's what happens:

• Message Delivery: Messages sent by the blocked person while they were blocked will not be delivered. Unblocking them does not retroactively send those messages. Message%20Delivery

• Contact Restoration: Unblocking a contact restores them to your WhatsApp contact list, assuming you previously had them saved. Contact%20Restoration

• Privacy Settings: They will again be able to see your profile picture, status updates, and "last seen" information (subject to your privacy settings). If you've set your "last seen," profile photo, or status to "My Contacts," they'll be able to see these again because they're back in your contacts (assuming they have your number saved as well).

• No Notification: The person you unblocked is not notified that you unblocked them. They will only know if they attempt to contact you and see that messages are now being delivered, or if they can once again see your profile information that was previously hidden. No%20Notification

• Re-Adding to Contacts (If Necessary): If you deleted the person's contact information from your phone's address book before blocking them, unblocking them in WhatsApp will not automatically re-add them to your phone's contacts. You'll need to manually re-add them if you want to see their name instead of their phone number in WhatsApp. Re-Adding%20to%20Contacts

• No Impact on Other Apps: Blocking and unblocking someone on WhatsApp has no effect on whether they are blocked on other apps or platforms.
