After completing the installation of Sizefox and creating your size chart, you will need to assign the appropriate products to that size chart.
When using the query matcher, you might notice that not all your expected filtered products will be displayed in the matching screen.

This happens because the query matcher screen only displays a sample of the whole product catalog.
For example, in the image above we can see a total of 10 raws per page, but our total catalog may be much larger.
Please note that this does not affect the performance of the widget. The matching conditions will apply to your entire product catalog regardless of your product being displayed or not.
Eventually, your new product pages, which did not exist at the installation of Sizefox | Connect, will be automatically detected upon receiving their first page visit. Therefore, if they fall within the matching conditions of a published size-chart, you can expect to see the widget appearing after the second page visit.
