Will messages from a person come if you unblock them in WhatsApp - briefly?
Unblocking someone on WhatsApp does not deliver any pending messages that were sent while they were blocked. Only new messages sent after unblocking will be received.
Will messages from a person come if you unblock them in WhatsApp - in detail?
If you have blocked someone on WhatsApp, the act of unblocking them does not automatically deliver any pending messages that were sent during the time they were blocked. When you block a contact on WhatsApp, any messages they attempt to send will fail to deliver and will not be stored for later retrieval once the block is lifted.
Once you unblock someone, you can start receiving new messages from them as usual. However, it's important to note that any messages sent while they were blocked will not appear in your chat history. This means that if there were crucial or important messages exchanged during the blocking period, those messages are permanently lost and cannot be retrieved by simply unblocking the contact.
For example, if you block a person on January 1st and then decide to unblock them on February 1st, any messages they tried to send between these dates will not be delivered to your WhatsApp. Instead, you will only start receiving new messages from that point forward.
In summary, unblocking someone on WhatsApp allows you to receive future messages but does not recover or deliver any messages sent while the person was blocked.
