If someone is blocked in WhatsApp, will their messages arrive after I unblock them - briefly?
If you have blocked someone on WhatsApp and then decide to unblock them, any messages they sent while they were blocked will not be delivered to your phone. This is due to the blocking mechanism that prevents the transmission of messages from a blocked user.
If someone is blocked in WhatsApp, will their messages arrive after I unblock them - in detail?
If you block someone on WhatsApp, the consequences for message delivery are significant and have several important aspects to consider.
Firstly, it's crucial to understand that blocking a contact on WhatsApp does not prevent messages from being sent. When you block someone, they can still send messages to your number as usual. However, these messages will not be delivered to you; instead, they will remain undelivered on the sender’s end. This means that the blocked user will see a single checkmark next to their message, indicating that it has been sent but not yet delivered.
Once you decide to unblock this contact, the situation changes. The previously undelivered messages from the time when the contact was blocked will not suddenly appear in your chat history. WhatsApp does not have a mechanism to backdate and deliver old messages that were sent during the period of being blocked. Therefore, any messages sent while you had the contact blocked will remain undelivered and will not be visible to you after unblocking.
However, it is important to note that new messages sent by the contact after you have unblocked them will be delivered normally. This means that from the moment of unblocking forward, communication can resume as usual, with both parties able to send and receive messages without any issues or delays.
In summary, while blocking a contact on WhatsApp does not stop them from sending messages, it does prevent those messages from being delivered to you. Once you unblock the contact, only new messages sent after the unblocking will be successfully delivered; previously undelivered messages will remain inaccessible.
