TikTok is moving stories to the main content feed, more specifically – in the "For you" and "Subscribe" (Following) sections.
What's the point
The implication is that users no longer have to go to a separate tab to view. An added benefit is the larger screen for viewing videos. Plus, this way, app creators can do away with the sidebar on the left.
For now, the new way of displaying stories works in beta mode and details about the transfer of stories are unknown.
