What message does WhatsApp display when you are blocked - in detail?
When a user is blocked on WhatsApp, the messages they send to the person who has blocked them will not be delivered and will display only one tick (indicating that the message was sent but not delivered) instead of the usual two ticks (indicating delivery). Additionally, the profile picture of the person who has blocked you may no longer be visible. If you try to call the person who has blocked you, the call will not go through and it will show a "calling..." status indefinitely without connecting. These are clear indications that your messages or calls are not reaching their intended recipient due to being blocked.
