I have noticed that the changes am making in the page sections, specifically on “Services wirh Slider” are not getting updated. If you Preview Changes you see your editing has taken effect, but when you refresh the site nothing has changed.
Lastly, how can I change the footer information in the “Powered by” Section?
Yes, That is what i said earlier.
You can edit /create pagebuilder elements in that single page itself no need to edit any page sections which is listed
down the page. Earlier i have shared the screenshot .
Pls go through this pagebuilder documentation –
