If you're creating variable products, this setting can be really helpful. How to use it depends on how you create your variable products. If your variable product has variations for all brands, it is very useful to enable this setting.
Variable products with variations for all brands
When this setting is enabled, the plugin will check each variable product to see if there are brands in the Invition Platform which are not connected to that product. If the plugin finds a missing brand, an action will be created to add this. These actions can be found at the 'Product updates' page.
Please note that this setting does not add the brands automatically, but it creates the action which adds the brand. We don't want to change all your data without you knowing, so we only do the suggestions and when you approve the data will be added.
Variable products with a selection of brands (e.g. all Apple phone cases)
When you want to create a variable product for a selection of brands, for example all variations for Apple smartphones, make sure this setting is disabled. Then you can select manually which brands you want to use for each variable product.
