One is paused by META due to a low interaction rate from customers or a low reading rate.
META regularly pauses certain templates. However, thanks to WAX, templates included in your campaigns are automatically relaunched. No action is required on your part.
If META sends you a message notifying you about a template being paused, please note that the WAX team also receives this notification. You can disregard this message, as the template will be automatically reactivated by WAX.
