I installed minimal version of latest stable Drupal 8. It does not include any HTML text formats so I had to add my own custom Full HTML text format next to default Plain Text.
It also doesn't include any content types, so I had to create my own Basic page content type with Body field.
When adding/editing content under body field it doesn't show the Text format field drop-down and I cannot select neither out of two formats, it just loads up some default CKEditor.
Also with minimal installation it doesn't include Administrator role. So I did create my own custom Administrator role and gave it all permissions, including under Filter, but still no effect, even though I'm user/1.
How do I get
Text format working/displaying on Minimal installation?
