I am still using the new editor which is going to become standard in WordPress shortly. I turned it on in this site several months ago, and while I still use the same editor you are using everywhere else, I am finding that by persisting with the new editor on this site it is starting to grow on me.
It is like most things that are new and different, you just have to keep trying. With only a few exceptions I can do everything I was doing in the old editor. So just in case your website changes at some point when it is rolled out to everyone; don’t panic. You should be able to turn on the old editor, or simply give the new one a try.
If you are stuck let me know and I will get the old editor working. I will try to put a Gutenberg video tutorial together in the next month or two to provide some tips on using it.
