Creating page content by using CMS page in admin and F-builder at the same time

You can use cms page to edit the homepage, no problem but you can't use cms page and builder to edit together

- When you edit by builder, then you need to click "Confirm" on the left corner to save edited things to cms page, that mean cms page will be updated whenever you click "Confirm" and the changes what you did in cms page directly will be lost. if you don't click "Confirm", you  can't see the content that you edited by builder after you disable the builder, so it is required to click "Confirm" when you want to save edited things by builder. 

- If you directly edit anything in cms page, you also can't see them when you edit the builder. So if you want to use Front-end Builder, please don't edit directly in cms page.
