Dit zegt ChatGPT over dit issue:
If messages you send in a WhatsApp chat are also being sent to other people unexpectedly, there are a few possible explanations and steps you can take to address the issue:
1. **Check for Forwarding**: Ensure that you haven't accidentally forwarded the message to other contacts.
2. **Group Chat Confusion**: Double-check that you aren't in a group chat. Sometimes, it can be easy to confuse a group chat with a one-on-one chat if you have similar contact names or group names.
3. **WhatsApp Web**: If you're using WhatsApp Web, ensure that your account isn't logged in on another device where someone might be sending messages on your behalf.
4. **Third-Party Apps**: Verify that you don't have any third-party apps connected to your WhatsApp that might be causing this issue.
5. **Account Security**:
- **Log Out of All Devices**: Go to WhatsApp settings and log out of all devices under the WhatsApp Web section.
- **Change Password**: If you suspect your account might be compromised, change your WhatsApp password.
6. **Reinstall WhatsApp**:
- **Backup Chats**: First, back up your chats to iCloud.
- **Uninstall and Reinstall**: Uninstall WhatsApp and reinstall it from the App Store. Restore your chat history from the backup.
7. **Update WhatsApp**: Make sure you are using the latest version of WhatsApp, as updates often fix bugs and security issues.
If none of these steps resolve the issue, it might be a good idea to contact WhatsApp support for further assistance.
