Copying math formulas to Microsoft Word suddenly pastes as plain text instead of rendered equations

Operating system

Windows

Joplin version

3.4.12

Desktop version info

Windows 11

What issue do you have?

Hi everyone,

I've been using Joplin for a while, and my standard workflow has been copying content containing math formulas from Joplin and pasting them directly into Microsoft Word. Previously, the formulas would render correctly as editable/formatted equations in Word.

However, today I suddenly found this method no longer works. When I paste into Word, the formulas just appear as plain text (without any markdown or LaTeX wrappers), meaning fractions, integrals, and other equations are no longer rendering properly.

Has anyone experienced this or know why it might have broken suddenly? Is there a setting I need to check, or has something changed in recent versions?

Any help would be greatly appreciated!
