Welcome back to The Information's 411.

This week, we talked about Amir's exclusive story that outlined Uber's many business problems. As he reported, UberPool loses lots of money. So the company has been working to cut those losses, but when it raises prices, fewer people use Pool. We discuss what that means for Uber's ambition to attract more customers and reshape transportation.

And then there's Twitch. Remember Twitch, the live-streaming platform Amazon bought in 2014? (You first read about that news in The Information, too.) Priya published an exclusive story this week about how the company is grappling with a declining user base and falling short of advertising revenue goals.
