Apple does not show whether it has been delivered.

Apple does not show whether it has been delivered. It depends. There are the following situations:

1. Network connection problem of the other party's equipment: the other party's equipment is not connected to the network or the network signal is unstable, which makes the message you sent unable to be delivered in time.

2. Receiver device settings: The message settings on the other device have been changed, and the sending status of the message cannot be displayed normally.

3. Blocking or rejecting: If the other party adds your contact information to the blocking list or turns off the function of receiving iMessage messages, the message you sent will not be displayed as delivered. So Apple doesn't show whether it has been delivered, it depends.
