What’s the difference between Sent (single tick) and delivered (double tick) messages on WhatsApp?

1. Internet Connection: If either the sender or the recipient has a poor or unstable internet connection, the message may not be able to reach the WhatsApp servers or the recipient's device.
2. Recipient's Device Offline: If the recipient's device is turned off or not connected to the internet at the time the message was sent, WhatsApp cannot deliver the message until the recipient's device comes back online.
3. Blocked Contact: If the sender has been blocked by the recipient, the message will not be delivered, and the sender will not receive any notification about it.
4. Temporary WhatsApp Server Issues: Sometimes, WhatsApp may experience temporary server issues that can prevent message delivery. These issues are usually resolved quickly, and the messages are delivered once the server is functioning normally again.
5. Deleted Account: If the recipient has deleted their WhatsApp account or uninstalled the app, the message will not be delivered.
6. App Compatibility: In some cases, if the sender and recipient are using different versions of WhatsApp or incompatible devices, messages may not be delivered.
7. Network Restrictions: In certain cases, network restrictions or firewalls implemented by internet service providers or organizations can interfere with WhatsApp's functionality, leading to message delivery issues.
8. Privacy Settings: The recipient's privacy settings may be configured to allow only certain contacts to send them messages. If the sender is not on the recipient's approved contact list, the message will not be delivered.
