Which social channel would require the use of the Social Studio Mobile app to publish content?

The Social Studio Mobile app specifically supports the management of social interactions and content publishing on various channels. However, not all social channels require a mobile app for publishing content. In this case, Twitter, Instagram, and LinkedIn typically have robust web-based management options that allow users to schedule, manage, and publish content directly from a desktop interface.

By saying "None," it emphasizes that all these channels can be managed effectively without the necessity of using the mobile app specifically for content publishing. The channels mentioned have alternative methods of content creation and publishing, meaning that the mobile app is not a requirement for these tasks. This reflects the capability of the Social Studio to offer flexibility in content management across different platforms.
