If your menu shows "Install Code" then you are using a version of B2B Ninja that was provisioned prior to Oct. 2018.
It's pretty quick and painless to update, and there are many benefits. Please shoot us a quick chat request, and we'll help you through the next steps. It generally takes less than 30 minutes once we're in contact.
Once updated, We auto-install our code via the script manager, so you don't have to ;-)
You can control your buttons under the "Form & Button" page.
If you need additional modifications to your buttons, or help with customizing your buttons further, let us know!
Note: If you installed prior to Oct 2018, you may have our button code installed directly on your theme. Contact us to migrate to the newest version, or get assistance with your existing code.
