Changes in supposed staging site pages just go live on real site.

Trying out the free version to make this is the best option for my client. However, the staging site doesn’t appear separate from the live site.

The orange admin bar indicating the staging site goes away once I try editing a page. Any update is pushed live.

What am I missing here?

Do I need to upgrade in order to have an entirely separate staging option? We need to update a lot of content before pushing live.

Do I need to have seperate login credentials for the staging site?

I have tried accessing the staging site URL via incognito browsing and still seems to divert to the live admin once updating a page.

I think I’m missing something here but don’t know what it is. Thanks!
