Don't have "get text from blog post" tick RTE

Hello! I can’t figure out how to style rich text because I can’t see the tick ''get text from blog post".

You already have it bound to the Post Body field, that’s what the big purple selector indicates.
The ticks are recently gone and replaced with a more modern UX, docs are catching up I think.

Get it. But how should I style the RTE? When I click “Disconnect Property” in the drop down menu, whole text disappears and there is nothing to edit.

You need to create some placeholder text you want to style. Headings, blockquotes paragraphs, etc.

Unbind it, create the elements you want, style them specific to that rich text element class, re-bind it.
