Just looking at starting my own blog for my clients and really puzzled that their is no preview a post option. Am i missing something? Pretty sure I used to be able to do this for clients?
Hi 
What do you mean by ‘preview a post’?
Hi! The option should still be there. You can find the steps in the following article:

Hope this helps! 
Thank you for the screenshot. Yes, this is not expected behavior. I would raise a support inquiry.
