Seeing "Devices out of sync" message
If you're seeing the warning "Devices out of sync," you may need to update your phone clock to the correct time. The date, time, and time zone settings on your phone should match your current location. If they don’t, you can update your clock in your phone’s settings. If your clock is set correctly but the warning persists, check your internet connection and restart your phone.
If the clock remains incorrect on your phone, your linked devices may be automatically removed after some time. You can always relink your devices.
For the future, we recommend setting your date and time to Automatic or Network Provided. With this setting enabled, your mobile provider will set your phone to the correct time. If the incorrect time is displayed even with this setting enabled, then there might be an issue with your network. Please contact your mobile provider to address the issue.
Note: If the issue persists, contact us through the WhatsApp Business app by going to Settings > Help > Contact Us.
