Edit page different layout

When I currently try to edit a page things have changed so there are no options for Add Media, the whole page has a different appearance. Instead it now only allows a Block to be added with limited formatting options. I have taken a screen dump of the way the Edit page looks on this website compared to another website of which I am the administrator which has the old feel. I have updated both sites to WordPress version 5.6. How can I add the screen dumps to this message? Please reply to this request to [redacted] well as the Forum. Thank you!
