Imessage does not show sent or read. Was it hacked?

When iMessage doesn't show that it has been sent or read, it can't be simply thought that this is the reason why the account was hacked. Some common iMessage problems include network problems, another device does not open iMessage service, or iMessage logs into the same account on another device. In addition, if both parties turn off the "Send read receipt" option in iMessage settings, neither party can see the read status. If you suspect that you are blocked by the other party, you can try to send messages from other numbers or devices, or contact the other party through third-party applications or methods to ensure that the problem is not a technical problem, but other reasons.
