Missed math symbols \bot and \perp about firamath HOT 4 CLOSED

\top (⊤) and \bot (⊥) are not created, but \perp (⟂) has been added already. Could please provide more information, e.g. version of the font, and a piece of code that can reveal your problem?

from firamath.

I am using most recent version of MikTeX. Fira fonts came with MikTeX. Problem with \perp was resolved after removing the command

%\def\perp{\mathrel\bot}

which I added long ago since \pert symbol was missed in Cambria Math. Other lines of my code follow:

\usepackage{fontspec}
\defaultfontfeatures{Ligatures={TeX},Renderer=Basic}
\setmainfont{Fira Sans}

\usepackage[math-style=ISO,bold-style=ISO]{unicode-math}
\setmathfont[Color=000066,Scale=MatchLowercase]{Fira Math Regular}
\setmathfont[range=\int,StylisticSet=1]{Fira Math Regular}

\begin{equation}
\label{1:01}
\tau_{n} \approx \sqrt{2\tau_{\|}\tau_{\bot}}
\perp\bot
.
\end{equation}

I will add them later.

Instaead of
%\def\perp{\mathrel\bot}

you should have used

\providecommand\perp{\mathrel\bot}

then you get no error if \perp was already defined.
