Old Sydney won't let me edit text on Homepage

I installed Sydney years ago - now I have the latest 1.55 version but it still has to be edited the old way (without Elementor that is not even installed since the updates have never added it as a plugin).

Is there a way I can update the site so it uses Elementor? Will it break if I do so?

Thanks in advance

Hello,

I would be glad to help you, but can you please provide a link to your website first?

Kind Regards, Roman.
