Anonymous/guest user edits/updates are not syncing correctly in Teams.

We’ve built a custom Teams meeting extension app that uses the Live Share SDK to display a shared editor in the meeting stage area. This allows all participants to collaboratively edit content, with changes syncing across everyone’s screens.
