Fix LaTex. It does not work and you know it does not work. It has been a Forum topic for years. And, it cannot be that hard to fix. This has been a problem since I first used theBrain many, many years ago. I am still a theBrain customer. I love everything about theBrain except, because of LaTex, I am continually going to something else (Obsidian is becoming my go to Note manager). I love theBrain and keep my subscription hoping that someday I will be able to use theBrain to manage my math notes.
