If you're experiencing issues with sending messages on וואצאפ, it might be due to a few reasons such as poor internet connection, outdated וואצאפ version, blocked by the recipient, etc.
Here are the steps you can follow to troubleshoot:
1. Check Your Internet Connection: Make sure that your device is connected to the internet. You can try to open a webpage in your browser to verify if your internet is working.
2. Update וואצאפ: Visit your device's app store, search for וואצאפ, and update to the latest version.
3. Check If You're Blocked: If you're unable to send messages to a specific contact, it's possible that you've been blocked by them.
4. Reinstall וואצאפ: If none of the above works, you may need to uninstall and reinstall וואצאפ. Remember to backup your chat history before doing this step.
If you continue to experience issues after trying these steps, you may want to contact וואצאפ support for further assistance.
