All new to this site. From the start, Latex is rendered as typed, not translated into mathematical typesetting. I realize there are duplicate question, eg
but I couldn't find any that actually seemed to resolve the issue. Ideas or suggestions?
Edit: as I found out through the below comments and answers, there are apparently other issues I am aware of to be broken: editing is limited as described in my comment below. I uploaded the image from my Ubuntu machine, in which I also see, and can use, the editing buttons; and in which Latex is rendered fine.
