Why I don't see editor and add media in my page?

I believe I might have had a similar issue, here is what I did. This may or may not be the same issue you had. It appears that WordPress 5.0 and higher has a new editor (Gutenberg) that is a little different from the one shown in the video which is the Classic Editor. But there is a quick fix, so I think (still a newbie). From the dashboard go to Plugins, Add New and Search for Classic Editor and then Activate once Classic Editor is selected. If you don’t like the look and feel of the Classic Editor you can always deactivate it in the Installed Plugins and switch back to the new editor. I also figured out how to add images within the paragraph using the new editor if you are interested. Hope this helps!

Something just clicked. I think it’s the browser I’m using. I’m using Chrome and they don’t normally display this. I used other browser, can’t remember the name, and it was fine. I will try it this evening or explorer. Thoughts?
