If I block a contact in WhatsApp and then unblock them, will I receive their messages - briefly?
If you block a contact on WhatsApp and later unblock them, you will not receive the messages they sent during the time they were blocked. However, any new messages they send after you have unblocked them will be delivered to your chat history as usual.
If I block a contact in WhatsApp and then unblock them, will I receive their messages - in detail?
When you block a contact on WhatsApp, the messaging application implements several measures to ensure that communication between you and the blocked contact is effectively halted. This includes preventing any new messages from being delivered or received by either party. Additionally, neither you nor the blocked contact can see each other's online status, profile picture updates, or other presence information.
However, once you decide to unblock this contact, WhatsApp does not automatically restore the previous message history. The system is designed in such a way that messages sent while the block was active are not delivered to your device upon unblocking. This means that if the blocked contact attempted to send you messages during the period they were blocked, those messages will remain undelivered and will not appear in your chat history even after you unblock them.
It is important to note that while previous message delivery is halted by the block feature, future messages sent after the unblocking process are fully functional. Once the contact is unblocked, any new messages they send will be received normally, and you can continue your conversation as if the block never occurred.
In summary, unblocking a contact on WhatsApp does not retroactively deliver messages that were sent while the block was in place. Only new messages sent after the unblocking process will be received.
