If you are unable to send messages to a specific person in WhatsApp and you are certain that they haven't deleted you, there are a few possible reasons for this issue:
Network or internet connectivity issues: Ensure that you have a stable internet connection. Poor network connectivity or a weak internet signal can prevent messages from being sent or received. Check if you can access other websites or apps that require an internet connection to verify if the issue is specific to WhatsApp or your network connection in general.
Contact blocking: Although you believe that the person hasn't deleted you, it's still possible that they have blocked you on WhatsApp. When someone blocks you, you won't be able to send messages to them, view their profile picture or status, and your messages won't be delivered to them. Double-check if you can see their profile picture and status, as this can provide an indication of whether you have been blocked.
Privacy settings: The person you are trying to message may have specific privacy settings enabled that restrict incoming messages. WhatsApp allows users to customize their privacy settings, such as allowing only contacts or selected people to send them messages. Make sure that the person has not set their privacy settings to exclude you from sending them messages.
Phone number or contact issues: Verify that you have the correct phone number saved for the person you are trying to message. Ensure that their contact details are accurately entered in your phone's address book, including the country code. It's also worth confirming with the person that they haven't recently changed their phone number.
App version compatibility: Check that both you and the person you are trying to message have updated versions of WhatsApp. Incompatibility issues can occur if one of you is using an outdated version of the app. Update WhatsApp to the latest version available on your respective app store.
Temporary technical issues: WhatsApp may experience temporary technical glitches or server-side issues that can affect message delivery. These issues are usually resolved within a short period. If you encounter this problem, try waiting for a while and then attempt to send the message again.
Other communication problems: It's possible that the person you are trying to message is facing issues with their device, such as a low battery, a malfunctioning app, or being in an area with poor network coverage. In such cases, they may not be able to receive your messages promptly or at all.
If none of these reasons explain why you are unable to send messages to the person in question, it may be helpful to reach out to WhatsApp support directly. They can provide more specific guidance and assistance based on your situation, helping to identify and resolve the issue.
