If I block a contact in WhatsApp, will they be able to see the old conversation - briefly?
When you block a contact on WhatsApp, they will not be able to view your profile picture or status updates, and your messages will no longer deliver to them. However, the old conversation history will remain visible to both parties; blocking only prevents future communication.
If I block a contact in WhatsApp, will they be able to see the old conversation - in detail?
When you block a contact on WhatsApp, they will not be able to see your previous conversations with them in detail. Blocking a user effectively removes their access to any future messages and prevents them from viewing your profile picture, status updates, or any changes made to your information after the blocking action has been taken.
However, it's important to note that if the blocked contact had previously saved or exported chat history, they might still have access to old messages on their device. Additionally, WhatsApp does not delete past conversations from either party's phone; rather, it prevents further communication and interaction between the two parties.
In summary, while blocking a contact on WhatsApp will prevent them from seeing new messages or updates, any previously saved chat history may still be accessible to them if they had stored it before being blocked.
