Math Assistant in OneNote M365 no longer calculates results

I’m a mathematics professor in higher education, and I’ve relied heavily on OneNote for Windows 10 — especially its Math Assistant feature — to support my teaching. While we teach at the university level, the mathematics involved is foundational: from basic first-degree equations to partial derivatives of multivariable functions, limits, definite and indefinite integrals, 2D graphing, and inequality plots. This isn’t advanced research mathematics — it’s core material for management and accounting students.

In the previous version of OneNote, I could write an equation, click “Math,” and immediately get the final result. That was extremely helpful for classroom demonstrations and student self-checking. In the current version (OneNote M365), the “Math” button still appears, and it does solve simple equations — but it fails to graph more complex functions and is significantly slower than the previous version.

Is Microsoft working to restore the ability to calculate final results and draw 2D graphs reliably, as the previous version did?

This feature is essential for teaching and productivity. I appreciate any clarification.
