Delay in dynamic data collection

I have connected the parent form with child form. As far the declaration of Kobo it will approximately take around 5 minutes to sync the parent form data with child form. But in my case it is taking more than one week. Can anyone help me out? Is there any settings or any option?, if this is the case then please note that there might by some syntax issues in your form. Maybe try uploading the XLSForm that is in the support article.
