@gidi there is a ticket to allow the preview of block themes, but it looks inactive.

I remember there are plugins to switch themes based on the user, so admins can make changes before switching to a theme for the public, but since the templates are essentially content, they don’t seem to work without affecting the active theme.

I suggest hiding blocks or areas you don’t need or need to be updated, using a plugin like Block Visibility, or setting a Staging site to make changes in a safe environment.

@gidi I see what you mean. I will see if there is a discussion with the Theme’s team. In the meantime, it is handy to use the “Edit Site” link from the corresponding template you want to edit to access it quickly.

@gidi I think it's just the home template. You must manually insert the rest of the templates into the pages.

@MediaActivist the one with Jetpack works fine for me.
