For a new product, collection, vendor, etc. to be filterable through an app's product selector they must be synced with our database. It should be pointed out that every product in the store will always appear in the product selector in the default results list, they just may not be found through the filters immediately.
Each app will automatically sync the store products, collections, vendors, etc. with our database once a week. At that point, they'll be filterable. It's possible to manually trigger this process so the database sync will occur sooner.
Within the product selector, it will indicate the date the filters were last updated. If it's not the current date, a link will be available to manually start the update. Select the "Update Now" link to start the update.
Note: The length of time for the update to complete will vary by store. As a general rule of thumb, it will take about one hour per 1000 variants.
