To change the text on the Add-to-Cart button on your bundles please follow the steps below:
Go to Translation
On the Fast Bundle app, navigate to “Settings” and go to Translation.
Find the Add to Cart text and replace it
In this section, you can assign your desired translation to every phrase in the Bundle.
To change the text on the add to cart button, search for "add to cart" in the search bar and find the phrase that you're looking for in the list. Type in your desired replacement and save.
