Microsoft word online isn't rendering equations correctly
I have An equation in the equation tools and when i insert it the brackets seem to disappear.
The issue seems to be with using Firefox as it renders correctly on chromium. My current research of the problem says it could potential be an issue with the Firefox MathML implementation but I'm not sure exactly how to test that let alone fix it. Is this an issue i should raise with Firefox or am i being dumb and missing an obvious fix?
Try to export/print as PDF and see if it renders.
If yes: That's a MS problem
If no: It's a problem with your pc
Maybe try a different browser like Edge Chromium to see if it works in their 1st party browser.
If that doesn't try to disable external add-ons and plugins.
