Prompt Title: Teams Live Captions Visibility.

There could be a few reasons why live captions may not be visible to all participants in a Teams meeting:

1. The live captions feature may not be enabled for the meeting. The meeting organizer or a presenter can turn on live captions during the meeting by clicking on the "..." button at the bottom of the meeting screen and selecting "Turn on live captions."

2. The live captions may not be visible to some participants because they have turned off the feature in their settings. Participants can turn on or off live captions by clicking on the "..." button at the bottom of the meeting screen and selecting "Turn on live captions."

3. The live captions may not be visible to some participants because of technical issues. It's possible that the captions may not be appearing due to a slow internet connection or an issue with the participant's device. In this case, the participant may need to troubleshoot their device or internet connection to resolve the issue.

If none of the above solutions work, it's best to contact Microsoft Teams support for further assistance.
