A "preview feature" is a feature that is currently available to the public but may be subject to change before it is officially launched. This means that any settings or configurations you have made may need to be adjusted in the future.It's important to note that preview features are still expected to work reliably and are not inherently unreliable or buggy. In fact, officeatwork strives to ensure that preview features are just as dependable as any other new feature.In some cases, a preview feature may require some manual configuration by officeatwork engineers. These efforts are provided as a courtesy by officeatwork, and we hope to receive feedback from users in exchange for making the feature available.
