Hi,
But I use it like the following
\definefontfamily[myfonts][rm][latin modern roman]
\definefontfamily[myfonts][mm][noto sans math]
\setupbodyfont[myfonts,rm,12pt]
\starttext
Test Noto Sasn Math Fonts
\startformula
a^2 \quad \sqrt{a}
\stopformula
\stoptext
I get the errors `Math error: parameter 'supshiftup' with id 51 in style 0 is not set'.
Is there some method to solve it?
