Managing sound and video settings during Teams meetings and calls for optimal communication
The fireworks live reaction is not available in all versions of Microsoft Teams. It is currently only available in the latest version of the app for iOS and Android devices. If you're using an older version of the app, you won't see the fireworks option.
You can check which version of the Teams app you're using by going to Settings > About. The version number will be listed under Version.
If you're using the latest version of the app and you still don't see the fireworks option, it's possible that your organization has disabled it. You can check with your IT administrator to see if this is the case.
I hope this helps! Let me know if you have any other questions.
Kind regards,
Jayzar
