Hey, thanks for the report. I can see that the LaTeX formulas are showing as plain text (for example, $x + y$) instead of rendering as math notation.

This looks like a bug in plan mode’s markdown renderer where it isn’t processing LaTeX syntax. I’ll pass this on to the team.

Bad news: in the chat interface, even the mathematical symbols can’t display properly now. OMG
