Numbering on MS Word document on MS Teams disappears

[QuentinO]

We are working as a team on a report saved as a MS Word document on MS Teams. Sine 17 August 2022, the formatting changes as soon as a second person opens the document in that the numbering disappears altogether. What is causing this glitch and how do I fix it?

I'm assuming that the document is created in a desktop Word and then opened in Web Word.

Not all features are supported by Web Word. It's possible that the formatting is using something that isn't supported.
